Note on submodule remote protocol

[htwangtw]

I had some unclear error messages with the test build on roboneuro, followed the docs to use CONP binder instance to debug.
The issue turn out to be submodules in my repository.
The remotes of the submodules have to use the HTTPS protocol.
This is a rather niche use case but I thought it might be useful to add in the checklist.

Hi @htwangtw thanks for the feedback! Log files forwarded by the https://roboneuro.herokuapp.com will be improved soon to provide clearer information.

The issue turn out to be submodules in my repository.

SSL verification is set true in repo2data configs, which would be the reason why submodule sync did not go through.

I will make sure that this 👆 goes into the documentation.

Thanks!

I see it's repo2data!

Thanks for the quick response.
The documentation and instructions for local tests are really clear 😊

So sorry, I wanted to say repo2docker, which is one of the core packages developed by the Jupyter community. Thank you for giving a NeuroLibre notebook a try!
