Incorrect breadcrumbs generated by raven.js

[mdamien]

After installing raven.js@3.0.4, it adds breadcrumbs data to the event.

But Sentry (8.4.0) is complaining that the breadcrumb is not valid: Discarded invalid value for parameter 'breadcrumbs'.

Here's the, redacted, value:

{
  "name": "breadcrumbs",
  "value": {
    "values": [
      {
        "category": "xhr",

        }
      }
    ]
  }
}

What's wrong the value generated by raven ? Is it a problem on raven or on sentry ? (because it seems to fit the Sentry API)

This is fine to ignore. Breadcrumbs didn't make it into Sentry 8.4, but will be in 8.5. This is effectively just a warning from the server saying the data isn't something it understands.

@mdamien – if the warning is irritating, you can go back to Raven 2.3.x until Sentry 8.5 is released. Raven 3.0.x pretty much just adds breadcrumb support.
