I think the problem is the new version of graphql-tools

I tried in ts and js mode, get the same problem

[PeterChen1997]

maybe relate to this #5262

@PeterChen1997 thanks for reporting! I was able to reproduce this and it's failing in our CI as well. I'll escalate this.

[PeterChen1997]

Thx! Waiting for the good news

[jtoar]

@PeterChen1997 We've got a fix for it here: #5378. I'll see about releasing a patch or maybe we'll just wait till the minor Tuesday, but since this is breaking, a patch feels more appropriate. But it's in canary if you want to try it out now and confirm:

yarn rw upgrade -t canary

[jherdman]

I can confirm that this works.

We just released a patch for this: https://github.com/redwoodjs/redwood/releases/tag/v1.2.1. Please upgrade and let us know!

yarn rw upgrade

After upgrading to version 1.4.0 this error returns.
