Column header mismatch: expected: 24 columns got: 26

[brynjagr]

You are missing the two relatively new columns fle-status and fle-encrypted-fields. As a consequence the lambda fails with an error.

Hi @brynjagr, The two fields that you mentioned above have already been added by us so this should not create any issue anymore.

Still, I tried reproducing your issue but couldn't see any lambda function break in my setup. Can you please help me with some more information like what exact error you saw and at what step? Because everything is working at my end.

Thanks for additional information.

Hi! Thanks for flagging this. I've opened #6, which adds the missing fle-status and fle-encrypted-fields columns so the parser expects the correct 26-column CloudFront access log format. This should fix the Lambda header mismatch error.
