The Airbyte UI stopped working today and shows an "unknown error". I found this error on the console: {"message":"Method Not Allowed","_links":{"self":{"href":"/api/v1/web_backend/check_updates","templated":false}},"_embedded":{"errors":[{"message":"Method [GET] not allowed for URI [/api/v1/web_backend/check_updates]. Allowed methods: [POST]"}]}. Was this a change to the API that wasn't backwards compatible with older versions of Airbyte?

Based on the information provided in the extracts, it's not clear if the error you're encountering is due to a backwards incompatible change in the Airbyte API. However, it's worth noting that Airbyte does not guarantee backwards compatibility for the

/web_backend/

endpoints as mentioned in a [previous support conversation](https://airbytehq.slack.com/archives/C021JANJ6TY/p1664915212477799). The error message you're seeing suggests that a GET request was made to the

/api/v1/web_backend/check_updates

endpoint, but only POST requests are allowed. This could potentially be due to a change in the API, or it could be a bug. If you've recently upgraded Airbyte, it's possible that there could be some compatibility issues. In a [previous support conversation](https://airbytehq.slack.com/archives/C021JANJ6TY/p1677870454997389), a user experienced issues with the UI after upgrading, which was resolved after the Airbyte team fixed permissions on the open source connector catalog JSON file. If you're still experiencing issues, it would be best to reach out to the Airbyte team directly for further assistance.
