Queries giving 404 on Retool Embed

I've followed the Retool Quickstart documentation, except in PHP instead of React. I've turned on Query Spoofing in the Beta and assigned my domain under branding.

The dashboard is loading in an iFrame, however the queries are giving me a 404 error.

How do I debug/fix this?

Thanks

Hi @Mike_Miner1 I see that you were able to solve this already with some internal folks by using the subdomain that you set up during the retool embed configuration -- glad to hear!
