Invalid options object. Copy Plugin has been initialized using an options object that does not match the API schema

[ASHBAW]

Description:
Creating a brand new angular based blank ionic 5 project gives an error when trying to run livereload:

Steps to Reproduce:
I create a brand new angular based starter - blank - Ionic 5 project via

ionic start test2

I then added the cordova android platform with the following command:

ionic cordova platform add android

I run the following command to do a livereload:

ionic cordova run android -l

Output:

ionic cordova run android -l
[INFO] Hardware device(s) found for android. Using --device.
> ng run app:ionic-cordova-serve --host=localhost --port=8100 --platform=android

Same here. I just created a new ionic project and added the android platform. Same error. I am on windows. Everything was setup from scratch.

same here , i have to build apk every-time just to test the native plugins

The solution (workaround) for me was to rollback the @ionic/angular-toolkit to the previous version, seems to be something up with v2.3.1.

npm i @ionic/angular-toolkit@2.3.0 -E -D

EDIT - Mention @dwieeb

Please someone help!! as I am facing same issue from yesterday and it is annoying as I was not able to find any solution yet. All I could figure out that when options.patterns is getting used looks like it is empty. I am not sure how to assign it.

@vibalani see my comment above.

[vibalani]

@SimonBrazell thanks a lot. I don't see the error now but when I run "ionic cordova run android --device -l -debug" it's been 10 minutes the app is still rendering and hasn't open. Hope it works but if I find any issues I will share here. Thanks again you were able to point to exact issue.

[SimonBrazell]

@vibalani I don't tend to use Android livereload a lot myself, but when I do I notice it does seem to take a long time to complete, hopefully a bit of patience will be all you need for that one 🙂

[Moinak99]

@SimonBrazell it worked ! , thanks a lot.

[vibalani]

@SimonBrazell the reason I mentioned it because from last 2 months I have been using Android livereload and it is up & running in 1 min or so. I saw a huge slowness and I might have messed up something while trying to fix this issue. Thanks!!

[SimonBrazell]

@vibalani oh right, maybe I'm thinking of iOS instead, good luck!
