I'm trying to deserialize a YAML file using JMSSerializerBundle with Symfony 3.3. Running this code:
$yaml = $this->serializer->serialize($obj, "yml");
dump($yaml); // This shows valid YAML content
$result = $this->serializer->deserialize($yaml, ObjCls::class, "yml");
produces: The format "yml" is not supported for deserialization. So, serializing works but not deserializing. The above code works well with json and xml, but not with 'yml'.
Is there some configuration I have to change in order to deserialize YAML?
It seems JMSSerializerBundle does not deserialize YAML (June 2017). I had to switch to XML. Too bad, I like YML format.

I use the openapi generator kotlin module to generate kotlin classes from my openapi.yaml file. The process works fine until I try to deserialize the received JSON in my code to a kotlin class using Jackson.
This is the generated class
data class Request (
#field:JsonProperty("name")
var name: kotlin.String,
)
This is the error I get
java.lang.IllegalArgumentException: Cannot construct instance of `...package.Request` (although at least one Creator exists): cannot deserialize from Object value (no delegate- or property-based Creator)
at [Source: UNKNOWN; byte offset: #UNKNOWN]
I noticed that when I remove the "#field:" part in the generated code, then everything works like a charm.
So now my question is can I either remove the #field from the generator or make Jackson deserialize it correctly?
The versions that I use are
jackson: 2.13.1
open-api-generator (gradle plugin): 5.3.0
I had the same error and registering the Kotlin Jackson module fixed it for me: https://github.com/FasterXML/jackson-module-kotlin
I am trying to convert some data to Json to send to the CloudFlare API. I am attempting to use Newtonsoft.Json.JsonConvert.SeriablizeObject() to accomplish this but I am getting the Intellisense error that the type name 'serializeObject' does not exist in the type 'JsonConvert'. I have the NuGet package Newtonsoft.Json installed but it does not recognize the SerializeObject() method. I am not sure what I am missing.
Its because you're calling the method wrong, remove the new operator from the line
var json = new JsonConvert.SerializeObject(updateDnsRecord);
to
var json = JsonConvert.SerializeObject(updateDnsRecord);
I'm attempting to extract data from AVRO files produced by Event Hub Capture. In most cases this works flawlessly. But certain files are causing me problems. When I run the following U-SQL job, I get the error:

I get the following error:
Unhandled exception from user code: "The given key was not present in the dictionary."
An unhandled exception from user code has been reported when invoking the method 'Extract' on the user type 'Microsoft.Analytics.Samples.Formats.ApacheAvro.AvroExtractor'
Am I correct in assuming the problem is within the AVRO file produced by Event Hub Capture, or is there something wrong with my code?
The Key Not Present error is referring to the fields in your extract statement. It's not finding the data and filename fields. I removed those fields and your script runs correctly in my ADLA instance.
The current implementation only supports primitive types, not complex types of the Avro specification at the moment.
You have to build and use an extractor based on apache avro and not use the sample extractor provided by MS.
We went the same path
When I try to serialize object containing Local date, I get following error:
csv generator does not support object values for properties
I have JSR-310 module enabled, with WRITE_DATES_AS_TIMESTAMPS and I can convert the same object to JSON without problem.
For now I resorted to mapping the object to another, string only object, but it's decadent and wasteful.
Is there a way for Jackson csv mapper to acknowledge localDates? Should I somehow enable JSR-310 specifically for csv mapper?
I had the same problem because of configuring mapper after schema. Make sure you are using the latest verson of jackson and its modules. This code works for me:
final CsvMapper mapper = new CsvMapper();
mapper.findAndRegisterModules();
mapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false); //Optional
final CsvSchema schema = mapper.schemaFor(PojoWithLocalDate.class);
// Use this mapper and schema as you need to: get readers, writers etc.
No additional annotations needed in Pojo class.
Is it possible to perform a file upload to DRF with HyperlinkedModelSerializer in a model which has a FileField?
I am using the coreapi File class from the utils package and coreapi complains about the File object not being a JSON primative (sic).
Looking through the code it looks like the schema has to say the encoding must be multipart form.
Where can I find a working example for such a file upload to DRF into a model with a FileField?
So... reading through the code I came across the encoding parameter for client.action.
If set to multipart/form-data, the file is correctly encoded and not validated as a JSON field but instead a body parameter.
with open('/Users/Jonathan/Desktop/test.png', 'rb') as f:
client.action(schema, ['incidents', 'create'], params={ 'file': utils.File('test.png', f) }, encoding="multipart/form-data")
Reading through transports/http.py and utils.py for the rest of the story….
