Hello,

I created a small module that creates and downloads a custom xls report from account_move. I used report_xlsx as a dependency. When I tested this module in two of our demo servers, it works perfectly. But when we install the module in our production server, when we click the option to download the report, an error appears. The weird thing is that the traceback is completely empty, with no explanation on why it is not working. Even in the server logs, it doesnt look like there is a problem. Im trying to find an explanation on why can my module work in the demo servers but not the production one.
