Hello!
We use ChatGPT business/enterprise with some internal MCP apps in our org workspace.
Everything was relatively fine, until yesterday evening we started to have issues connecting to existing MCP Apps or refreshing them in ChatGPT.
Our MCP Apps are under OAuth (Azure). They worked nice for last few weeks, but yesterday something has changed in ChatGPT and when we try to connect the same very MCP App - we get the following issues.
- First issue is “Type mismatch: expected CONNConnector, got AppsSDKApp”.
Steps to reproduce:
Try to connect to existing MCP App in the org workspace.
We get the notification “Something went wrong with setting up the connection”
In DevTools (Network) we see only 1 issue: error 500, “Type mismatch: expected CONNConnector, got AppsSDKApp”.
It failed on https://chatgpt.com/backend-api/aip/connectors/links/oauth/callback
Request Method: POST”
We suspect an internal ChaGPT issue.
Our MCP app(s) still work fine when we invoke them in ChatGPT chats, the connection is established, we can invoke tools/apps from those “failed” at connection MCP Apps.
It is not good to have such error that confuses our users.
- Another issue “Failed to update app actions. Please try again” happens when we try to Refresh → Confirm the existing MCP App:
Refresh is “successful” , we see the “Confirm” button.
But when we click Confirm, we see the error notification in red “Failed to update app actions. Please try again”.
We do not see any issues reported in DevTools. Maybe, it is .js issue in ChatGPT?
Thus, we are blocked refreshing the MCP App(s).
We did not have any of 2 issues until yesterday. We assume both of them appeared at the same time (March 30, first noted at ~ 8 pm UTC).
We did not do any code updates (MCP Server side). All our MCP Apps with “UI” are impacted by these issues.
I will try to add more screenshots down below in comments.
Does anyone experience same issues?
