Converting circular structure to JSON error when pushing some error logs

[raphaelquati]

Description

I'm using iife modules (in a Angular 6 application).

Environment

• SDK 1.11.0
• SDK instrumentations: Web SDK, Web Tracing
• *OS: Windows 11
• Browser: Edge

Javascript console:

 @grafana/faro-web-sdk:instrumentation-console
 TypeError: Converting circular structure to JSON
    --> starting at object with constructor 'Object'
    |     property 'element' -> object with constructor 'Object'

The error occurs here:

I think is related to #587

The error (angular error):

ERROR Error: ExpressionChangedAfterItHasBeenCheckedError: Expression has changed after it was checked. Previous value: 'ngIf: true'. Current value: 'ngIf: false'

Hi,

I ran into the same issue today.
I am using "@grafana/faro-web-sdk": "^1.12.0",
Is the fix already released

[raphaelquati]

I've updated my application to use 1.12.0 (I'm using iife modules), and the error was gone.

@AdityaRanjanSingh

I see the issue. There was an unprotected stringifier left which even doesn't to this place.

Fixed with this PR

Thanks for reporting
