Hey Team,

I've noticed a breaking change when using Microsoft.PowerApps.CLI version 1.9.8 - pac unpack

Here is the error.

Sorry, the app encountered a non recoverable error and will need to terminate. The exception details have been captured and will be forwarded to the development team, if telemetry has been enabled. Exception Id:759d1bad-96a1-4baa-8ae3-46ca250935bb.

Cheers Brad

For those affected by this issue since November, there is a new PAC version 1.10.4 that restores the ability to pack and unpack canvas apps. Works as advertised.. again.. for now.

Re: [ERROR] Microsoft.PowerApps.CLI version 1.9.8 - pac unpack error

Here is a screen shot of the error on my local machine. I noticed the command is "pac canvas unpack"

Here is a link to a blog describing what I am trying to achieve.
Canvas source code tool integrated with Power Platform CLI | Microsoft Power Apps

Step 1 -
pac install latest
Step 2 -
pac canvas unpack --msapp dxc_demoapp_c91ef_DocumentUri.msapp --sources src
Step 2 fails when using latest pac toolset, but is working when I use Version 1.9.4

Appreciate the support!

Yes, what I'm saying is that "unpack" is not a command in pac, so what are you executing when you see this error?

I have tried using the CLI on my local machine and in my Azure Devops Pipelines.
This happens when you use the latest version of the Microsoft.PowerApps.CLI version 1.9.8 (released yesterday)
