Google - BigQuery Location Error (dataset was not found in location europe-west1)

I am running a query on BigQuery and everything runs properly. However, when trying to save this query as a new table (in BQ) I get the following error:
enter image description here
"Not found: Dataset mycompany-data:google_analytics_de was not found in location europe-west1 "
The aforementioned table location on BigQuery is europe-west1.
I have double-checked for spelling errors and access permissions, but this error persists whatsoever.
Can you assist me with this?

ADLA/U-SQL Error: Vertex user code error

I just have a simple U-SQL that extracts a csv using Extractors.Csv(encoding:Encoding.[Unicode]); and outputs into a lake store table. The file size is small around 600MB and is unicode type. The number of rows is 700K+
These are the columns:
UserId int,
Email string,
AltEmail string,
CreatedOn DateTime,
IsDeleted bool,
UserGuid Guid,
IFulfillmentContact bool,
IsBillingContact bool,
LastUpdateDate DateTime,
IsTermsOfUse string,
UserTypeId string
When I submit this job to my local, it works great without any issues. Once I submit it to ADLA, I get the following error:
Vertex failure triggered quick job abort. Vertex failed: SV1_Extract_Partition[0][0] with error: Vertex user code error.
Vertex failed with a fail-fast error
Vertex SV1_Extract_Partition[0][0].v1 {BA7B2378-597C-4679-AD69-07413A143E47} failed
Error:
Vertex user code error
exitcode=CsExitCode_StillActive Errorsnippet=An error occurred while processing adl://lakestore.azuredatalakestore.net/Data/User.csv
Any help is appreciated!
Since the file is larger than 250MB, you need to make sure that you upload it as a row-oriented file and not a binary file.
Also, please check the reply for the following question to see how you currently can find more details on the error: Debugging u-sql Jobs

Error 22 when scanning for available WiFi-Networks using CoreWLAN

I use the following code to scan for all available WiFi-Networks:
[[CWInterface interface] scanForNetworksWithSSID:nil error:&err];
Usually I get a NSSet of Networks but sometimes I get the following error:
The operation couldn’t be completed. (com.apple.coreWLAN.error error
22.)
Error Domain=com.apple.coreWLAN.error Code=22
I haven't find anything about that error code 22. Is there a documentation or a solution for this?
Because I had another problem with CoreWlan(http://stackoverflow.com/questions/9943833/cwinterface-returning-no-data) i replaced it with Apple80211.framework.
This also is a workaround for this one...
