wrangler tail: Error parsing response body!

[Electroid]

🐛 Bug report

Describe the bug

When a Worker has a console.log of an Object, such as:

console.log({ key: 'value', value: 1.234, objects: [ 1, '2'] })

And wrangler tail --format=pretty is used, it returns an error:

Error parsing response body!
This is not a problem with your worker, it's a problem with Wrangler.
Please file an issue on our GitHub page, with a minimal reproducible example of
the script that caused this error and a description of what happened.

Reproduce the bug

A list of steps to reproduce the bug.

1. Publish a Worker with the above code snippet somewhere in the execution.
