500 Internal Server Error when uploading tar file

[eatherne7]

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] Traceback (most recent call last): File "/usr/local/lib/python3.6/site-packages/flask/app.py", line 2073, in wsgi_app response = self.full_dispatch_request() File "/usr/local/lib/python3.6/site-packages/flask/app.py", line 1518, in full_dispatch_request rv = self.handle_user_exception(e) File "/usr/local/lib/python3.6/site-packages/flask/app.py", line 1516, in full_dispatch_request rv = self.dispatch_request() File "/usr/local/lib/python3.6/site-packages/flask/app.py", line 1502, in dispatch_request return self.ensure_sync(self.view_functions[rule.endpoint])(**req.view_args) File "sar2html.py", line 400, in uploadFiles updateThread = AppContextThread(target=updateDb(hostList, app.config['UPLOAD_FOLDER'])) File "sar2html.py", line 103, in updateDb s2df.columns = s2col File "/usr/local/lib64/python3.6/site-packages/pandas/core/generic.py", line 5154, in setattr return object.setattr(self, name, value) File "pandas/_libs/properties.pyx", line 66, in pandas._libs.properties.AxisProperty.set File "/usr/local/lib64/python3.6/site-packages/pandas/core/generic.py", line 564, in _set_axis self._mgr.set_axis(axis, labels) File "/usr/local/lib64/python3.6/site-packages/pandas/core/internals/managers.py", line 227, in set_axis f"Length mismatch: Expected axis has {old_len} elements, new " ValueError: Length mismatch: Expected axis has 5 elements, new values have 6 elements [pid: 25916|app: 0|req: 1/4] 172.17.65.101 () {48 vars in 1004 bytes} [Fri Nov 19 14:12:55 2021] POST / => generated 290 bytes in 6060 msecs (HTTP/1.1 500) 2 headers in 99 bytes (93 switches on core 0)

Steps to reproduce the behavior: I followed the git clone, install requirements, installation process. Everything looked to install fine, the app starts fine and i can browse the app without error.

Expected behavior Uploaded data is ingested into the app for viewing through the BUI

Internal Server Error

The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

I think the report file is broken somehow. I can check if you attach the tar file to the incident report.
