+If an error of the following type occurs when creating or deleting an actor/participant:

+And fixing diagram code does not get rid of this error and rendering of all other diagrams results in the same error, then you need to update the mermaid version to (v\<MERMAID_RELEASE_VERSION>+).

 ### Grouping / Box
 
 The actor(s) can be grouped in vertical boxes. You can define a color (if not, it will be transparent) and/or a descriptive label using the following notation:
