Hi @arkiboys ,

Thank you for posting query Microsoft Q&A Platform.

It seems you are passing values to parameters to dynamically to frame path to your file. And, that path doesn't exists on storage or your are passing incorrect values.

Please consider below points while dynamically framing path to your source using data flow parameters.

• If your parameter is string type kindly pass values in single quotes.
• Make sure your dynamic expression written correctly using parameters.
• Make sure you pass the values in to your parameters with correct data. I mean the path should exists on storage.

Hope this will help. If not, Please feel free to share your implementaion along with parameters and expression written. So that we can repro and help on resolution.
