Error loading debug manifests - SPFx Extensions 2

[AntyfrizZz]

Hello,

I posted question here, but i am not sure if the issue is closed, that someone will receive notification or something. - #1175

I have the issue with Error loading debug manifests. I can run debug only in Chrome . When i try to do it on other browser, I get the error.
SPFx 1.7.0
Node - v8.9.4
I ran gulp trust-dev-cert
It is Application Customize Extension
I scaffold new App Customizer with latest version of yeoman and the issue is still in

Nothing. Sad.

Best Regards,
Yavor

thx @AntyfrizZz - can you be slightly more specific on what do you mean with " When i try to do it on other browser" - which browser and which version, so that we can help you?

[VesaJuvonen]

@AntyfrizZz - also - your steps do no include gulp serve command when you are testing, so can you provide the repro steps, so that we know the steps which you did. Thx.

@VesaJuvonen ,

Sorry for the lack of information

On your first question
Firefox 64.0.2 (64-bit)
Microsoft Edge 38.14393.2068.0

On your second
Yes, i did run gulp serve.
On the attached files you can find newly scaffolded project (with nothing modified by my side). When i run gulp serve, i can start debugging it on Chrome, but when i try to do it on the browsers mentioned above, i get the error.

Hey all,
just wanted to let you guys know I also have this issue, it works fine if I use IE but not Edge when I develop Extensions.
IE: 11.523.17134
Edge: 42.17134.10
Node: v8.15.0
Thanks,
David

Can you provide the following?

• verify you are testing this against latest SPFx v1.7.1
• what environment (SPO / SP2019)
• URL that's generated & used to load the extension on the page
• screenshot of the command prompt used when running gulp serve to run the command
• and ideally, screenshot of the error in the browser's NETWORK tab
