Good day,
I'm working to authenticate a Bubble.io app but encountering an error when trying to call the OAuth2 function, as shown in the image. Any assistance would be appreciated!

Hello Dennie Verhagen,

Please refer to the following forum post on the Bubble support forum, which discusses the same issue:

https://forum.bubble.io/t/text-too-long-for-this-field-ms-login-oauth-2-0/370595/20?page=2

The “Text too long for this field” message is related to a known limitation when saving OAuth keys. This message is returned when trying to save data that exceeds the 2,000-character limit. Bubble saves the token returned by your OAuth provider when a user signs up or logs in with an OAuth 2.0 User-Agent flow API. Currently, there isn’t a way to increase the character limit. A workaround shared by a user can be found on the Bubble Forum thread. OAuth User-Agent Flow Text Too Long for This Field

If the workaround does not resolve the issue, please feel free to message me over private message. We can then connect offline to further investigate whether this issue originates from the Azure side.
