Apple App Site Association - denied because the CDN told us to stop with HTTP status 404: SWCERR00305 Network error -- {"cause":"gzip: invalid header"}

Hello,

I am currently working on Automatic Strong Passwords for my flutter app, but my apps gets following error in the device console of my iphone, when debugging from Xcode.

Request for '' for task AASA-1D8C0610-7098-4F04-B2BF-EE364CA9AC70 { domain: ap….ec….app, bytes: 0, route: cdn } denied because the CDN told us to stop with HTTP status 404: SWCERR00305 Network error -- {"cause":"gzip: invalid header"}

I think this is the reason for the following message:

[AutoFill] Cannot show Automatic Strong Passwords for app bundleID: BUNDLEIDENTIFIER(CENSORED) due to error: Cannot save passwords for this app. Make sure you have set up Associated Domains for your app and AutoFill Passwords is enabled in Settings

The AASA File is on following path: https://censored.censored.app/.well-known/apple-app-site-association

The content of the file is:

{ "applinks": { "apps": [], "details": [ { "appID": "TEAMID(CENSORED).BUNDLEIDENTIFIER(CENSORED)", "paths": ["*"] } ] }, "webcredentials": { "apps": ["TEAMID(CENSORED).BUNDLEIDENTIFIER(CENSORED)"] } }

and the response headers are following from the api with the AASA file:

content-encoding: gzip
content-security-policy: default-src 'self' http: https: data: blob: 'unsafe-inline'
content-type: application/json; charset=utf-8

Can anyone help me with this issue?

I am working with a physical iphone 12 with ios-version: 16.0 (20A356a)

Thanks for your help in advance.
