hi @Harishkanagvel

it is likely some of your xlsx transformations is causing this. you can try to comment some parts and try again until you get a not corrupted xlsx, you will be able to identify which xlsx helper call is causing that problem and probably be able to adapt it and fix it.

Try running with the admin user credentials the first.
The Authorization header in this case should look like
Basic YWRtaW46YWRtaW4=
Does this work?
