Hello @arkiboys
There might be some malformed records in the JSON files that are causing the schema inference to fail.
check if there are any changes in the JSON files that are causing the issue. You can compare the JSON files that are processed successfully with the ones that are failing to see if there are any differences.
If the issue persists, you can try to isolate the problem by running the data flow with a smaller set of JSON files. This can help you identify if the issue is related to a specific file or a group of files.
