Mermaid previews generate 'e.ForEach' type errors on some node shapes

    • Closed Issue created by Olliver Schinagl @olliver.schinagl

    Summary

    Some of the more fancier node shapes generate: Encountered an error while rendering: TypeError: e.forEach is not a function when connecting

    Steps to reproduce

    Create a markdown document, write some mermaid code, click the 'preview' button (or commit and see the rendered doc) or put it in an issue, such as this one :)

    Example Project

    flowchart TD
  id1[ok]
  id2[[fail]]

  id1 --> id2
  id1 --> id3[/fail/]
  id3 --> id1

    What is the current bug behavior?

    image

    (further more, the error doesn't go away until clicked away :S)

    What is the expected correct behavior?

    No error and it is rendered properly, as can be seen in the live mermaid editor

    Output of checks

    This bug happens on GitLab.com

    Possible fixes

    This may be related to running an older version of mermaid-js? otherwise it is integration between the two components.
