Error fetching app record: Problem while uploading build on test flight App store

Xcode shows build uploaded successfully but not visible on test flight (Even after waiting for 2-3 days).

Tried to upload build using Transporter app but getting errors as shown in above screenshots and delivery logs below:

INFO: ContentDelivery version 2.14.8 (14038). INFO: Show Progress: Contacting Apple Services… ERROR: 404: received status code REQUEST CREATE CONTAINER (ASSET_UPLOAD); not found

I am confused what exactly is this error and what to do in order to solve this.

It's strange. No answer on this issue?
