Body:

I’m trying to deploy a .NET Core console application (.NET 8) to Heroku, but I’m encountering an issue where the dotnet command is not found when the application is started. Here’s a summary of what I’ve done:

1. Project Structure:

   • My project directory contains the solution and the Procfile.
   • The Procfile is located in the root directory: C:WorkspaceMainProjectsMYPROJECT.
   • The .csproj file is located in C:WorkspaceMainProjectsMYPROJECTMYPROJECT.ConsoleApp.

2. Procfile Content:

   worker: dotnet MYPROJECT.ConsoleApp/bin/Release/net8.0/MYPROJECT.ConsoleApp.dll
   

3. Heroku Configuration:

   • Set the buildpack: heroku buildpacks:set https://github.com/jincod/dotnetcore-buildpack.
   • Generated and added SSH keys.
   • Configured the Heroku API key.

4. Deployment Steps:

   • Initialized Git and committed the project.
   • Created a Heroku app and added the remote.
   • Pushed the code to Heroku and scaled the worker.

5. Environment Variables:

   • Converted appsettings.json to Base64 and set it as APPSETTINGS_BASE64 on Heroku.

Despite following these steps, the deployment log shows that the dotnet command is not found:

/app/worker.1: /bin/bash: line 1: dotnet: command not found

Deployment Log Excerpt:

2024-05-19T14:57:52.491062+00:00 app[worker.1]: /bin/bash: line 1: dotnet: command not found
2024-05-19T14:57:52.529056+00:00 heroku[worker.1]: Process exited with status 127

Questions:

1. Why is the dotnet command not being found on Heroku?
2. How can I ensure that the dotnet command is available for my worker process?
3. Is there any additional configuration needed for the buildpack or the Procfile?

Any help or pointers to resolve this issue would be greatly appreciated!
