Uncaught TypeError: can't access property 26, Z is null

[jaimeiniesta]

Describe the bug

The ErrorTracker UI has a JS error that prevents it from connecting as a LiveView.

The UI shows fine, but the topbar never finishes the loading effect. There's a JS error in the developer console:

Uncaught TypeError: can't access property 26, Z is null

To Reproduce

I've seen this in 2 different apps, both in development and production.

LiveView versions 1.1.8 and 1.1.11
ErrorTracker 0.6.0
Phoenix 1.7.21

Expected behaviour

ErrorTracker UI should load and set up the LiveView properly.

I got the same issue, but saw the message TypeError: null is not an object (evaluating 'Z[Q]') in my JS console.

For anyone else running into this, it's fixed on the PR tagged above. For a temporary workaround, install from github, until an update is published on hex.

defp deps do
    [
      ...
      # install error_tracker from github because of https://github.com/elixir-error-tracker/error-tracker/issues/158
      {:error_tracker,
       github: "elixir-error-tracker/error-tracker", tag: "update-phoenix-liveview"}
    ]
  end

This is correct @petrus-jvrensburg

Hopefully I'll be able to push the new release this week. Past few months have been extremely busy.

Hi! is it the same thing with OP's error log?

This has been fixed by #159, which is now merged. A new version of the ErrorTracker will be published soon.
