Hi,
I'm using a pipeline in ADF and the pipeline Copy data activity us using a rather complicated expression for FilePath. It is dynamic content, which includes concat, substring, length, sub functions. After I click 'Debug', I'm receiving the 'BadRequest' notification with no option to find out what's wrong.
I have used the expressions separately under 'Sink' in Copy data activity, then as a variable. None of these worked.
The content works with expression received from a notebook - this is usually not an issue with other pipes.
I made sure the content is not wrong by testing it in another environment, modified in appropriate language and I received the result I expected.
Please help.
