Hi @sagar ,
What is the current Data integration unit for the CopyActivity? Would you please increase the units and try again. Thanks!

Hi @sagar ,
Thanks for posting query in Microsoft Q&A Platform.
Is kind of error will come if some wrong with parquet file i guess. especially with version.
Is your getting this error with any specific file or all files? I tried to copy some dummy parquet file my end and I dont see any issues. I feel its more about something wrong with your file.
If other parquet files are good to process and then see version of them and try to get error file also in similar version to process.
Please let us know how it goes. Thank you.
Hi @sagar , Just checking if you get chance to share updates. Thank you.
