Anything else relevant?

Hi, can you try to use ng add @angular/bazel@next?

[hugodes]

Hi @alan-agius4,

Same thing here

[alan-agius4]

Is it possible to share a reproduction?

[hugodes]

@alan-agius4 I can, but privately.

I would try to reproduce it in a public repo but error doesn't give me any insight as to which file this is coming from.

[elvisbegovic]

@hugodes can you share all your *.json files (ie. angular.json, tsconfig.json, tslint.json...) related to angular ? In a zip please

[hugodes]

Hey again @istiti ,

Sure here you go:
angular.zip

[elvisbegovic]

Ok, In your angular.json you have a unnecessary comma at line 20 "src/assets",
Even if you remove it it will not compile do to many others comma, please delete theme in line 20, 155, 183, 184, 233

Then retry temporary by running npm uninstall @angular/bazel then ng add @angular/bazel@next

[hugodes]

@istiti thanks !

Do you think it would be a good idea to change the error from:

Invalid JSON character: "]" at 20:11.

to

angular.json: Invalid JSON character: "]" at 20:11.

?

[alan-agius4]

Yeah it is.
