I am trying to use fabric lakehouse files connector in Azure data factory for some transformations. If I read the single file in source, it works, but when I read multiple files with wildcard,
at Source 'SourceData1MillRowDataSampling': Operation failed: "BadRequest", 400, GET, https://onelake.dfs.fabric.microsoft.com/dae9c95a-b5ce-4c48-b967-e8a31e45aded?upn=false&resource=filesystem&maxResults=5000&directory=source_data&timeout=90&recursive=false, BadRequest, "WorkspaceId and ArtifactId should be either valid Guids or valid Names"
Thanks in advance
Can you share the expression where you use the wildcard ?
For now, it use pretty simple expression, to read files starting with patient_details and ending with csv.
concat('source_data/patient_details','*','csv')
Hello @Amira Bedhiafi In the folder, I have multiple files with same schema having prefix patient_details and suffix as csv.
Here is the wildcard pattern I used.
concat('source_data/patient_details','*','csv')

Hi Jatinder Luthra ,
Apologies for delay in response. Is the issue resolved for you?
Did you write the expression by clicking on 'Add dynamic content' or directly in the text field? Kindly use 'add dynamic content' for writing the expression.
@AnnuKumari-MSFT Thanks for checking back. This is not resolved as bug has been identified with this connector. I am working with Azure support on this, and got an ETA of mid November for this fix.
