BigPicture returns the 500 internal error when used as a power-up from Trello

[ArtGee]

I have tried reinstalling and installing again, signing out and in, but the error still persists when trying to open the BigPicture window from the Trello board:

HTTP Status 500 - {"token":"755c8b5d333c8b34ca89041d8e56bf6f.c41290c38fbccf947db1fb063ded28ec.Fri Mar 27 11:12:59 UTC 2020","code":"softwareplant.common.internal_exception","description":"Please refer to the following erorr id: \u003cp/\u003e 755c8b5d333c8b34ca89041d8e56bf6f.c41290c38fbccf947db1fb063ded28ec.Fri Mar 27 11:12:59 UTC 2020"}

As we do not develop the Power-Up, we would recommend reaching out to the developer directly via https://wiki.softwareplant.com/display/DOCUMENTATION/About+BigPicture+Trello
