Unable to use body attribute in tag

I have a project that has a login call that returns a JWT token which I inject as a header in other calls using a tag to recover the token from the body of the call. It worked until recently when it suddenly stopped.
In the tag editor, it returns this error:


The response of the call is very simple:

```json
{
"token": "eyJhbGciOiJSUzI1NiIsInR..."
}
```
When trying to filter the string directly from the response window using the filter `$.token`, it returns an array containing the string instead of a string, as has always happened before.


Start in the Insomnia tag editor and reproduce the issue with the shown JSON response and the $.token filter. Compare the returned array with the expected token string and trace the response-body extraction behavior. Done means the tag can recover the token as a string for use in a request header.
