How to get the description of exception when you handling an error, for example if the data type of a field is incompatible PDI throws you offending row by any reason. And so how to get the explanation?
For getting the description you can catch using the field Error descriptions fieldname, and set some name, that will be attached to the flow.

When exceptions occur in a UIPath project I have an email that is sent out with the exception info included. There seems to be an issue though where I can only see where the error occured by looking at the selector information such as:
Cannot find the UI element corresponding to this selector:
<html app='chrome.exe' title='Microsoft Dynamics GP' />
<webctrl aaname='Add' idx='1'
parentid='a00000000000000008549000000030009000000000001000000000000' tag='DIV' />
This info and the stack trace or any other info is not really helpful for quickly finding the source of the problem. I have looked through the UIPath documentation and forum and found only the this question, which seemed to point to using the exception.Source to show the name of the activity where the error occurred. exception.Source only returns “UiPath.Core.Activities” though instead of "Type into Copy Job# 'INPUT'" in the following example:
This obviously causes a big problem with exception handling. How can I easily return the source with each exception?
When your selector fails, you will end up with a new object of type UiPath.Core.SelectorNotFoundException. However, until the team at UiPath decides to add the Display Name into the inner exception, there is little you can do in this particular case.
Take the following example - the first line shows the Inner Exception, and the second one in red is essentially just the exception being rethrown. Note that only the latter one contains the Display Name property.
The Source itself will usually be of type UiPath.Core.Activities, but since this is just the type's name, we don't have any link to the faulting object. Here's what you can do:
Add some details to your exception. You don't want to do this for each activity, but you could have certain blocks of try-catches (example: logging into the system consists of three individual activites, and they reside in one block).
Rethrow the exception. That way the Display Name will end up in the execution log file.
I am new to Data Profile Viewer. I just created a package in SSIS which contains a Data Profiling Task Component. I am using the Sample database of Adventureworks2012 and I am creating an XML file through it using Employee table. But when I am trying to view the XML in Data Profile Viewer and selecting the Candidate profile Key it is showing me the below error:
Drill down query completed with error: The error message is:
System.ArgumentNullException: 'dataType' argument cannot be null.

Anyone having a knowledge on this how to resolve it. I am not able to find on Google.
Thanks for your help.
Try to add Polybase feature to your instance.
I have code to capture screenshot on test failure. What I'm doing right now is naming the screenshot with "TestContext.CurrentContext.Test.ID + "_"+ TestContext.CurrentContext.Test.Name". I want to add test failed message to it something like "Message: OpenQA.Selenium.NoSuchElementException : no such element: Unable to locate element: {"method":"css selector","selector":".applicationTitleSteps"}". Is there anyway to do this?
You can get read the Exception message as string by simply casting your Exception object. Perform string manipulation options like splitting to get the required value and concatenate with your current name, which you are giving for the screenshot while saving.
Your exception catching code should be like this, catch(exception ex).
I have an attribute tlost with the definition below in the XSD file. I have tried both use="required" and use="optional".
<xs:attributeGroup name="defense">
<xs:attribute name="tlost" use="required" type="xs:decimal"/>
</xs:attributeGroup>
In the XML document I am trying to import I will get a value like the following:
<defense ast="0" category="special_team" tlost="0" int="0"/>
I am executing an SSIS package that takes the tlost value and inserts it into a sql database table. The column in the database table has a datatype of DECIMAL(28,10) and allows nulls.
When I execute the package, the previous values work perfectly and the data is inserted. However, when I get a value where tlost="" in the XML file, the package fails and the record is not inserted.
In the data flow path editor, the data type for tlost is DT_DECIMAL. When I check the Advanced Editor for the XML Source, the Input and Output properties have a data type for tlost as decimal [DT_DECIMAL].
I can't figure out why this is failing. I tried to create a derived column and cast it as a (DT_DECIMAL, 10) data type. That didn't work. I tried to check for a null value and replace with 0 if null, that didn't work. So I just ignored the column all together and in the Derived Column task, I replaced the tlost column value with (DT_DECIMAL, 10) 0 to just insert a 0 value and ignore whatever is in the xml file, and the job still failed with the following error message:
Error: 0xC020F444 at Load Play Summary Tables, XML Source [1031]: The error "Input string was not in a correct format." occurred while processing "XML Source.Outputs[defense].Columns[tlost]".
Error: 0xC02090FB at Load Play Summary Tables, XML Source [1031]: The "XML Source" failed because error code 0x80131537 occurred, and the error row disposition on "XML Source.Outputs[defense].Columns[tlost]" at "XML Source.Outputs[defense]" specifies failure on error.

Please help. I have exhausted everything I can think of to fix this issue. I am processing hundreds of files, and I can't keep fixing bad data files every time this issue occurs.
Can you please try these
1 - Change to data type to string in xsd and before loading into tables take care of data type conversion.
2 - If possible generate the xsd by passing your xml and then verify the data type and use it accordingly ...
rest of the xsd can be changed accordingly...
below is screen grab of what I tried. hope it helps]1
I am trying to export the contents of a SQL Server 2005 table to a csv file using SSIS. In the Data Flow Task I have a OLE DB Source for the table and a Flat File Destination for the file.
When copying the data I started getting a failure on one of the column on a certain row and following some investigation found the problem was with comma's in the data below
Data Issue (nvarchar255)
errors code l075 showing,,,re test.
OLE DB Source for Comment col
Derived Column
Given that this was the issue I created a Derived Column object between the source and destination and destination objects and tried filtering out the comma's using a replace REPLACE(Comment,","," ") but the same column is still failing with the below errors.
Destination Component
Exception
[Inspection Failures Destination [206]] Error: Data conversion failed.
The data conversion for column "Comment" returned status value 4 and
status text "Text was truncated or one or more characters had no
match in the target code page.".
[Inspection Failures Destination [206]] Error: Cannot copy
or convert flat file data for column "Comment".
[SSIS.Pipeline] Error: SSIS Error Code DTS_E_PROCESSINPUTFAILED.
The ProcessInput method on component "Inspection Failures
Destination" (206) failed with error code 0xC02020A0 while
processing input "Flat File Destination Input" (207). The
identified component returned an error from the ProcessInput
method. The error is specific to the component, but the error
is fatal and will cause the Data Flow task to stop running.
There may be error messages posted before this with more
information about the failure.

The PrimeOutput method on component "Inspecton Failures Source"
(128) returned error code 0xC02020C4. The component returned

The meaning of the failure code is defined by the component,
but the error is fatal and the pipeline stopped executing.

Ok, the problem actually appears to be a hidden illegal character in the text
In the image below the top line shows a square before the re test string. The comment column in the database is an nvarchar which apparently uses a different character set so I can not just use the CHAR(13) + CHAR(10) to replace the carriage return.
The fix involved converting the field from an nvarchar to a varchar then performing a replace on the converter ? character resulting in the corrected second ling in the image
SELECT ID,
REPLACE(REPLACE(CAST(Comment AS varchar(255)),'?',' '),',',' ') Comment
FROM tblInspectionFailures WHERE (ID = 216899)
The conversion requirement is detailed here
This does not should like an ideal solution to me but it does work. Does anyone have any other options.
Without replacing comment column can you create another column and map the new derived column to destination column and see.
