UNSUPPORTED_CONSTRAINT

HTTP 422 · Unsupported constraint

What it means

The job asks for a constraint the optimizer does not implement. It is refused rather than solved approximately, so a plan never quietly ignores something you asked for.

What to do

Remove the constraint named in the error, or contact us if you need it.

Can I retry?

No. The same request will fail the same way until something about it changes.

Quote the request_id from the error if you contact us about it.
