How to solve deployment error on Heroku bin/*-heroku?

Question

go

Hello. There is a small project on Go. I'm trying to put it on Heroku and I get an error:

The structure of the project itself:

Which bin folder he wants to move and where is unclear. In the repository for the example go - applications, too, I did not notice any bin folders.

What am I doing wrong and how to finally deploy the project?

Answer 1

If src is at the root of the project, then Go's buildpack doesn't know how to build the project. Depending on what is used to check dependencies, certain tools are used during the build.
Additionally, the project root is missing a Procfile.
