PowerApps CLI 1.7.2 Issue

[gfpierce]

Hey all,

I'm having an issue on a PCF after updating to 1.7.2. My project builds fine, but when I run an npm start on my project, I get this error: UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'compileTime' of undefined.

Here's a screenshot with more information:

The error tells me the issue is on line 67 of pcf-scripts.js, from within the pcf-scripts package. Here's a screenshot of that line and a few relevant lines around it:

So my first thought to fix this issue was to just roll back to a previous version. I plugged "pac use 1.5.5" into the terminal, got confirmation that it moved the CLI to the correct version, and proceeded. The error persisted. I started a brand new project, initialized from scratch, put CLI to 1.5.5, and ran that project, only to find the same error.

So I looked into my package.json to find that the pcf-scripts and pcf-start modules in my projects were both still on version 1.7.2, and that rolling back the CLI didn't roll the packages back with it. So from there I ran "npm install pcf-start@1.3.1" and "npm install pcf-scripts@1.3.1" in my project and finally the npm start command ran without issue. I'm not sure if I actually had to roll all the way back to 1.3.1, but it seemed a good idea to roll back to a common version between the two packages.

Hope this helps if someone else runs into the same problem.

Hi @gfpierce , 

Thanks for reporting.

There were a few posts regarding the issue with pac cli 1.7.2. lately (like this one: https://powerusers.microsoft.com/t5/Power-Apps-Pro-Dev-ISV/PCF-NPM-START-WATCH-Erroring-Out-with-8-1...)

A downgrade to pcf-start@1.6.5 should be enough.
As posted in the other thread, a fix should be provided soon: https://powerusers.microsoft.com/t5/Power-Apps-Pro-Dev-ISV/PCF-npm-run-build-Error-self-signed-certi...

Kind regards,

Diana

Thank you, Diana!

This should be fixed with the latest update on the pac CLI which has the hotfix for this issue 

>> pac install latest

>> pac use latest

1.7.3 (Latest)

revert if you have made change to package.json for pcf-start 

    "pcf-start": "^1"

>> npm install pcf-start@latest

Let me know if there are any questions. 

Thanks,

Hemant
