Foam Graph is blank

[pyreton]

Open Foam Graph opens the panel, but it is blank. My best guess is this is because I am on the VSCode for Insiders build in order to get native M1 Apple Silicon support. (Foam Graph worked fine on previous Intel laptop using standard VSCode)

[ValentinTrinque]

Not on M1, but graph is also blank.

Can you see if anything shows up in the Foam log? https://github.com/foambubble/foam/blob/master/docs/features/foam-logging-in-vscode.md

@ValentinTrinque
thanks for this, I recognize the error and where it's coming from.
by any chance to do you have a repo I can reproduce it from? I have not been able so far

I'm not getting anything in the Foam logs when the Graph is blank. If I reload the window and then try to view the graph then it becomes visible.

BUT if I delete a link/node, then the graph isn't refreshing and I'm seeing the below logs:

I found the issue, it was related to how wikilinks were being resolved when in presence of a definition.
This will be fixed by #502

[riccardoferretti]

this has now been fixed as of 0.10.3 - can you confirm?

[pyreton]

Confirmed - thank you

[pyreton]

Unfortunately the foam graph intermittently stops updating again, and when I close it and re-open, it is blank.

I just upgraded to the latest version of Big Sur. (But it was working sometimes after the upgrade)

[pyreton]

Looks like I can repro:

1. Quit VSCode and reopen
2. Open graph to side, see graph
3. Edit text files for a while, notice graph stopped updating
4. Try closing and re-opening graph, see it's blank
5. GOTO 1
