Debugging custom visual PowerBI desktop errors

sjkp — Wed, 15 Jun 2016 06:30:26 GMT

So I have created a few custom visuals, and everytime it gets really anoying when you have to track down an error that only appears in powerbi desktop.

Is there anyway to attach a javascript debugger to the powerbi desktop process? That would really make debugging a lot easier.

Right now the error I'm getting are:

Error Message:

An error occurred while rendering the report.

Stack Trace:

Microsoft.Mashup.Host.Document.JavaScriptException: An error occurred while rendering the report.
   at :line 0

JS Error Message
Script error.

So my custom visual gives me a script error, or maybe it is the powerbi desktop client, how would I ever know if I cant debug, or get some better error messages. Worst thing is that the error in the above case is periodic, so I can't reliably reproduce it.

I'm running powerbi desktop 2.35.4399.601 64-bit (maj 2016) - on windows 10 enterprise. And my custom visual worked fine before the introduction of the sandbox feature (e.g. in the march powerbi desktop version).

Any help would be much appreciated.

I'm having this exact problem, did you find a way around this? Or a way to debug?

2017 no answer and no option to debug errors in power bi desktop. The best we have seems to be the error message in the details you can copy from the error popup.

There's no way to turn debugger mode one unfortunately but you might try to get more logs by enabling "Enable tracing" at Options of Power BI Desktop.
