Included version of zone.js removes Promise.withResolvers

[ajaffie]

Description

Promise.withResolvers is broken by the included version of zone.js via @opentelemetry/context-zone.

See open-telemetry/opentelemetry-js#4354 for details.

Steps to reproduce

In an app with @grafana/faro-web-tracing 1.8.2, type Promise.withResolvers in the console.

Expected behavior

It is a function.

Actual behavior

It is undefined.

Environment

• SDK version: 1.8.2

Context

For a workaround, I added the following to my package.json:

"overrides": {
  "@grafana/faro-web-tracing": {
    "@opentelemetry/context-zone": "1.25.1"
  }
}

I'm not sure if this is going to have any unwanted side-effects yet.

@ajaffie with Faro 1.10.0 we updated the all otel deps.
Does this solve your issue?

I can confirm that it works with the latest 1.13.3 version however I had to manually pin the zone.js version in my package.json like so

"overrides": {
     "zone.js": "0.14.3"
   }

This is the version that includes the fix for the Promise.withResolvers() removal angular/angular#53630

Heads up: with the next Faro release we don't include ZoneContextManager anymore.
It's causing problems very often and it's not needed by the default otel instruments we add.

Context manager is of course injectable via the web-tracer config.

 initializeFaro({
   instrumentations: [
     // ...
     new TracingInstrumentation({
       contextManager: new ZoneContextManager(),
     })
 ]
