Thank you for spotting this. How did you find it? How is this a blocker for you (just for my own curiosity)?
I'm running the CI to test on a non forked branch and will get back for merge.

I confirm that CI tests are passing. I successfully created a connection from a UI with a build on this branch.

Yes, I have TypeScript definitions for AirByte API which is generated from this config file, and this issue leads to a wrong definition which is:

type WebBackendConnectionCreate = {
  // properties
} & {
  connection: unknown
}

and the expected is:

type WebBackendConnectionCreate = {
  // properties
}

For me, I have to maintiain a patch memo and remind my self every time when the definition is generated. It is really a head burden.
