Hi Amardeep Singh

Could you please let me know which Azure service you are trying to deploy your application to and are you using App Service build in GitHub Actions, or are you deploying from CI/CD pipelines using App Service build?

Hi Amardeep Singh

If you're using Git version 2.13 or later, you can enable long path support by running the following command in your Git Bash or command prompt:

git config --global core.longpaths true

If possible, consider restructuring your project to shorten the paths. This could involve moving the project to a directory with a shorter path or renaming folders to have shorter names.

Review your project for any unnecessary files or packages that can be removed or excluded from the build process. This can help reduce the overall path length. If you have a lot of packages or dependencies, consider cleaning up your repository by removing unused packages or using a .gitignore file to exclude certain files from being tracked.

If the above doesn’t work, open the.git/config file in your repo and add:

[core]
    longpaths = true

Then restart your build or re-clone the repo.

Hope this helps!

Please Let me know if you have any queries.
