Hello @Abhishek KM Welcome to QnA,

The error message you're seeing in your Azure Data Factory pipeline suggests that an index was outside the bounds of an array. This can occur when you're trying to access an element of an array that doesn't exist.

We can think of basic troubleshooting steps such as,

• Can we run the workflow via Dataflow?
  If the error is occurring intermittently, check the pipeline runs to see if there are any patterns or trends. Look for any specific data or activities that might be causing the error.
• Check that the input and output schemas match the data being used in the pipeline.
• If you're using custom code in your pipeline, review the code and make sure that it is handling arrays correctly.

Did you try to implement any error handling for any of the activities (Anything related to unzip files in ADLS)?
