If not, could you confirm what data source you are connecting to and what version of the product you are using?
Thank you and have a good day,

Sorry for the delay in responding. I have found that you opened a case with the Support team and that you managed to resolve the issue on your own? If so, please feel free to share your resolution here in case this could help future readers.
somehow the data has been corrupted that's why this error pops out when we tried to run the extracts after renamed the fields.
To resolve this, we have recreated the new datasource using the same custom sql and replaced the old datasource with new one. this resolves the issue.
Please let me know if you have any questions.
