We are trying to run a pipeline, which was working about 3 months ago, with the same input data source, but we are receiving the following errors:

InternalServerError executing request

ErrorCode=FlowRunSizeLimitExceeded, ErrorMessage=Triggering the pipeline failed due to large run size. This could happen when a run has a large number of activities or large inputs used in some of the activities, including parameters.

    The final solution was to leave the datasource schema empty and set Allow schema drift = true in the pipeline source. After applying this change, the pipeline was able to process the source file correctly and load the data. This indicates that the issue was related to schema interpretation or compatibility within Azure Data Factory, and that allowing the source to handle schema changes dynamically resolved the problem without requiring changes to the source file itself.
