Question

App Platform: Could there be a "allow_headers" option for CORS?

Hey there.

I am getting the CORS error: “Request header field authorization is not allowed by Access-Control-Allow-Headers in preflight response.”

This is due to not being able to set “allow_headers” in the App Specification file. (This key does not yet exist.)

Is there any way to do something about this?

Stay healthy! Nick

You can actually do it by download the yaml file and adding it manually.

- cors:
    allow_headers:
    - '*'
    allow_methods:
    - GET
    - OPTIONS
    - POST
    - PUT
    - PATCH
    - DELETE
    allow_origins:
    - prefix: http://localhost:3001

I am building an embedded app into another website. I would like to set “Access-Control-Allow-Origin” to “" and “Content-Security-Policy” to "frame-ancestors https://.xxx.com”

Is it possible to do so?

I’m having the same issue. I want to allow certain headers in my requests. Any idea on how to solve it?
