Issue:

When authenticating the vSphere Plugin version 4.2.0 or 4.2.1 with Pure1, there is an error reported when you click Authenticate:

Error validating token.
Invalid issuer: JWT validation failed.

Illegal base64url character: ' '

This is due to line breaks being copied into the window when the JWT was copy/pasted in.

Workaround

To workaround this issue, copy the JWT to a simple text editor like Windows Notepad:

Then go to the end of each line and type Delete on your keyboard to pull the next line up to the top. Repeat this until all lines are on a single line.

Then copy and paste the JWT back into the vSphere Plugin and click Authenticate.
