Thanks for reporting. I created this on sandbox and the logs remain silent. Also the graph is shown.

I fell on the same trap today... so just adding my 2 cents to this issue....

Same code produces same problem with

So : Probably the solution is just that we didn't do the yarn install before using the extension ? The documentation is a bit unclear on this point (either composer --update or git clone ...)

@antibarbie Thank you for your comment. I guess "I Could NOT reproduce it when installing the 3.0.0 with composer --update." was a decisive information. Indeed this extension is only meant to be installed with Composer. I updated the documentation accordingly to make this clear and move out the MermaidJS update information to a separate developers only file.

@RhinosF1 I suspect that you cloned in this extension rather than using Composer. Is this assumption correct?

RhinosF1 commented 3 years ago

Git submodule but composer should be setup to run composer install. This is the second time composer has done weird though that I've been asked about. You can see our MediaWiki install under miraheze/MediaWiki and composer stuff in the puppet repo under extensionsetup.pp

RhinosF1 commented 3 years ago

I can still reproduce this on https://socdemwiki.miraheze.org/w/index.php?title=User:RhinosF1/sandbox&action=submit after whatever updates have happened in the last 3 months including that server being reinstalled.

Thank you for your feedback. It appears that @paladox was able to figure out what is going on and provided a pull request. Much appreciated.
