The Git LFS integrity check ensures that all referenced Git LFS files in a push have been uploaded properly. If the check detects referenced files that have not been uploaded, you will receive an error message and your push will be blocked.
To resolve the error message, you must reinstall your local Git LFS client to ensure that the referenced Git LFS files can be properly uploaded in the future.
Reinstall Git LFS.
git lfs install
Push all referenced Git LFS files.
git lfs push --all origin
