Recently we started getting error code 1131 "InvalidAPIEndpoint" seemingly out of nowhere.
We are making a game in Unreal Engine 4.23 and have a dynamic variable which allows us to change between our production and development environment. I have manually verified that we are setting the correct Playfab title ID with the "Set PlayFab Settings" blueprint method, but we are getting the following error unless we restart the editor:
"The URL for this request is not valid for this title. The correct API endpoint is https://TITLE_ID.playfabapi.com/" (where TITLE_ID is our correct title id)
We have never had issues with this before, but it started happening within the last week or so.
From a development point of view, this is not a huge blocker, however, the exact same problem arises when we build our development and production apps for release, which, as you can imagine, is a bit bigger problem for us. We are building for ios and android, if it is relevant.
To me it seems like there is some caching going on inside the plugin for Unreal, or perhaps somehow in the editor. The strange part is that this wasn't a problem last week. It might be that we have changed something to trigger this behavior, but a first glance through our history, it does not appear that we have touched this.
We have tried updating the plugin with newest from master (as-of 2nd June 2020), and of course recreating project files, deleting intermediate folders, and so on.
Any help on this matter would be much appreciated!
