To Reproduce

We have been unable to reproduce the issue locally, both while attempting to build the app standalone, as well as attempting to run the integration tests locally as well. However, it has been failing consistently in our CI pipeline, while attempting to debug this issue: Pull Request.

Current vs. Expected behavior

Our test application was building fine and passing our integration tests on Next 14:

However, after updating to Next 15, and also updating other dependencies (React, etc.) our builds are no longer successful, in turn our tests are timing out:

And occasionally we saw this error appear, however due to the nature of GHA (I believe), we're not able to get the full picture:
