Environment

VCF Operations for Networks 9.0.0 and 9.0.1

Cause

For vidm, csrf token is managed by backend server BE and set in browser based on redirection from vIDM.

VCF Networks for Operations GUI reads this cookie and saves the csrf token in its session for pdf and csv exports.

Sometimes, there is a space getting appended to this token due to the position of the cookie in the browser and thus we see this issue.  

 

Resolution

This is a known issue affecting VCF Operations for Networks 9.0.x. There is currently no resolution.

As of now, no workaround is available for affected vIDM users

Local user admin@local can be used to download the CSV and PDF

Additional Information

Similar issue: Attempting to download a previously generated VCF Operations for Networks 9.0.x support bundle sometimes results in a "HTTP 401 Unauthorized" error being generated
