Hey there! I'm having a pretty rough time getting Meltano running on DigitalOcean App Platform. I feel like I'm configuring my ui correctly, and it's running, but I'm running into the same CORS issues regardless of the combination of

MELTANO_UI_SESSION_COOKIE_DOMAIN

MELTANO_UI_SERVER_NAME

and related env vars I set.

meltano ui setup APP_HOST

doesn't seem to help either. As far as setup goes, I'm just deploying a

meltano/meltano:latest

image with some extra steps to copy in my configs (nothing weird). Also probably not the root of the issue, but I'm also getting

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at <https://data-eng-jbk9t.ondigitalocean.app/api/v1/plugins/installed>. (Reason: header 'x-json-scheme' is not allowed according to header 'Access-Control-Allow-Headers' from CORS preflight response).

weirdness in the console.

@sam_mccord You’re seeing CORS because apparently the domain that hosts the webapp is not the same as the domain being connected with to reach the API. Are you accessing the app at

<https://data-eng-jbk9t.ondigitalocean.app>

?

I am, but I can also visit https://data-eng-jbk9t.ondigitalocean.app/api/v1/plugins/installed should I not be able to if the api is on a different domain?

Glad you figured it out! Let us know if we can help we anything else 🙂
