500 Internal Server Error when uploading tar file #15
Description
Description:
I use the provided sar2ascii tool to generate a tar file. When i attempt to upload that data into sar2html either via the BUI or using curl i receive a 500 - internal server error in response.
Running the app interactively i can see it generates the following error message:
[2021-11-19 14:13:01,876] ERROR in app: Exception on / [POST]
