It seems that the Docker was not able to execute all parallel builds.
The solution I found is:Run the setup with option: ./nodebb setup --skip-builds Manually run the build in serial mode: ./nodebb build --series
That solved the issue.
Upon getting SSO working for wordpress and nodebb, I now cannot access my admin panel. Whenever I try to I get a "too many redirects" error. I'm essentially locked out now.
@CJ-Infantino you can disable plugins from the command line:
./nodebb reset -p nodebb-plugin-sso-wordpress
