Random Unknown Error when creating a new Diagram

[ane-gabriela]

Unfortunately I couldn't find a pattern but on XWiki 9.11 I randomly get Unknown Error when creating a new diagram

Environment: Windows 10, XWiki 9.11, Chrome 89, Diagram Application (Pro) 1.16-rc-2

I cannot reproduce with v1.16 on XWiki 12.10.6. I reloaded the diagram creation page tens of times (both on Firefox and Chrome), including after clearing the cache and I never got the error popup you mention. The error message from the JavaScript console log is not new, see #136 .

I've reproduced this error only on XWiki 9.11.
On XWiki 12.10.5 it didn't reproduce.

I reproduced this on XWiki 12.10.5 with Diagram 1.17.3.

I had installed Diagram app version 1.17.3 on top of the community 1.2 version.

@petrenkonikita112263 this ticket concerns diagram 1.16-rc-2 which was compatible with 9.11 (the minimum compatible version was bumped to 11.10 on #197, for diagram 1.17 ).

I don't reproduce on 15.10.10 but I am pretty sure I saw this before. Leaving open for now in case we see it again.
