ERRCONNREFUSED and Undefined URL when using Visualize Dataverse Environment

[tsileo-wdi]

HI Michael,

Thanks for providing this tool. I'm having trouble getting the visualization via Graphviz working. I'm wondering if it's only a local problem with my setup, or if there is something I missed that isn't documented anywhere (at least that I can find!).

I have installed the latest stable release of Graphviz 9.0.0 on my local Windows 11 PC. I exited and re-started VS Code just to be safe. When I try to use Visualize Dataverse Environment, I get this error:

Error running command mme2k-powerapps-helper.visualizeEnvironment: A system error occurred (connect ECONNREFUSED ::1:80). This is likely caused by the extension that contributes mme2k-powerapps-helper.visualizeEnvironment.

And in the Output pane I see:

GET undefined/api/data/v9.1/solutions?$filter=isvisible%20eq%20true&$expand=publisherid($select=friendlyname,customizationprefix,publisherid,uniquename) ...

I do NOT have a URL defined for the graph visualization API (as I understand it, I don't need that if I have GRaphviz installed on my machine).

Is there something else I neeed to do to get Graphviz configured and working correctly with PowerApps Helper?

thanks!
Tony
