Coverity scan error 'Project is invalid' - ruby-on-rails

Question

I use coverity for my rails application, but I can't upload any build.
I tried it with the Coverity Scan Self-Build. It runs without any problems, but when I upload my .tgz file, it fails with the following message:
Please fix the errors below.
Project is invalid
I used the following commands:
$ ~/Downloads/cov-analysis-linux64-8.5.0.3/bin/cov-build --dir cov-int --no-command --fs-capture-search ./

Afterwards I tried to upload the file myproject.tgz.
I also tried to use travis for uploading my first build, but it also fails with the following message:

Tarring Coverity Scan Analysis results...
Uploading Coverity Scan Analysis results...
Coverity Scan upload failed: ERROR: Project is invalid.
It also says Project is invalid. And since the build is from travis, I can't look into the logs.
The references file config/initializers/cookies_serializer.rb looks like this:
# Be sure to restart your server when you modify this file.
Rails.application.config.action_dispatch.cookies_serializer = :json
The third possibility is the command line upload. Here is the log:
$ curl --form token=<TOKEN> \
--form email=<MY_EMAIL> \
--form file=#/<PATH_TO_MY_APP>/myproject.zip \
--form version="1.0" \
--form description="Initial" \

And here is an excerpt of my .travis.yml file:

# commands to run before the install

build_command_prepend: ""
build_command: "--no-command --fs-capture-search ./"
branch_pattern: coverity_scan
I also tried this with the build command option --fs-capture-search ./app/, so just all application files are scanned.
Does anyone know why this error occurs?
Thanks in advance!
EDIT: added command line example

Answer 1

I believe the error message here is complaining that the project you're trying to commit your results to in SCAN isn't correctly configured. From your other question How to setup a Travis Rails project to submit to Coverity Scan?, you have this in your travis.yml. Did you update this to point to the correct project?
