Hi , I am facing the issue.
This issue is when I am running the pipeline from Synapse. I the dataflow , when I am trying to read data from change feed.
When I am running the full load , it is working. But when I choose to load for incremental load , it is giving below error.
Pipeline Id - 0b97ec95-15a8-4348-94e5-524802dc76b1
and DF run Id - ef6ffd02-ef05-4c3d-99d2-ac78a8dcfe52

    Hi @Anonymous ,

    Thank you for posting query in Microsoft Q&A Platform.

    From the error message, it seems your data flow trying to read data from some file which is not found. Kindly check is your change feed data avaialble?

    Also, When you say change feed you mean to say enabled some feature in dataflow? Kindly share your source and sink details along with detailed steps of dataflow implementation to understand issue better and help. Thank you.
