No url found for submodule path 'dist' in .gitmodules fatal error

I am trying to deploy my app to git pages and I have status failure for GitHub pages.

When I am start "pages build and deployment" in Action, I have a next problems:

1) Build > Checkout > Fetching submodules:
  /usr/bin/git submodule sync --recursive
  /usr/bin/git -c protocol.version=2 submodule update --init --force --depth=1 --recursive
  Error: fatal: No url found for submodule path 'dist' in .gitmodules
  Error: The process '/usr/bin/git' failed with exit code 128

2)Deploy > Deploy to github pages:
Error: Error: No uploaded artifact was found! 
Please check if there are any errors at build step.

Did I do something wrong?

Check the content of your .gitmodules file:

If it includes only one entry [submodule "dist"], with a module path dist, without URL,
Then delete the .gitmodules file entirely, add, and commit.
(Note: as in here, check if you has a dist (no trailing slash) entry,a and remove it if you do).

Then try again the deployment process.
