Pass raw sentry payload JSON to captureException?

[cameronmcefee]

Hello!

The following question is dumb, but humor me: I'm writing a plugin for Sketch which runs in a JavaScript-like environment that is actually thing JavaScript wrappers around Objective C 🙃 . Needless to say, there is not an out-of-the-box solution for Sentry, because whatever method by which the data is transmitted is not supported.

However, a component of the plugin is a webview which does exist in a JavaScript environment, and I can communicate between the two. I'm thinking that the most practical way for me to actually capture exceptions in the non-supported layer would be to pass the Sentry payload through and then send it from the @sentry/react instance I have running in the webview.

So, I have two questions:

1. Can I extract the payload JSON of a captureException request before it is sent?
2. Any chance there are docs for how to send that payload via the API before I go reverse-engineering it?

As a hacky solution, I imagine I could probably save the contents of beforeSend in a global variable somewhere and pull from that. It's no hackier than the rest of the situation, but I'm hoping that the SDK just has a built in method to generate the payload from an error.

To answer my own questions with something that works as ok as can be expected…

1. On the layer that doesn't support sentry sending requests, in beforeSend I emit an event to the webview layer with the contents of the event, and then return null.
2. In the webview layer, I have a function that receives the event object and then sends it via the @sentry/react sdk using:

   Sentry.getCurrentHub().getClient().sendEvent(payload)

It's ugly, but it is better than no Sentry at all
