Invalid reference format, help

[kexinhuang12345]

Hey, I want to use Binder for a demo for one of my project. Everything was good but it suddenly returns this error when I opened it today:

Waiting for build to start…
Picked Git content provider.
Cloning into ‘/tmp/repo2dockerp4oovtki’…
HEAD is now at 307bb54 fix small bug
Using DockerBuildPack builder
Step 1/5 : FROM node:
invalid reference format

I tried to refresh but no good. Could you help me what I should do to fix it? Thanks!

Hi! Looking at your GitHub repo, you are using a Dockerfile to build the environment. This is considered advanced usage of mybinder.org. Here are some resources:

• Configuration files for Binder: https://mybinder.readthedocs.io/en/latest/config_files.html
• Advanced Binder usage: https://mybinder.readthedocs.io/en/latest/tutorials/dockerfile.html
• A minimal example of what your Dockerfile needs to be compatible with Binder: https://github.com/binder-examples/minimal-dockerfile
