This is a very serious issue. This line breaks everything now:
https://github.com/niftylettuce/frisbee/blob/master/src/index.js#L289

If you pass a JSON string it will be spread into letters. If you pas a FormData object it will be spread as a simple JS object.

Normally, you should pass a FormData object as a body and the the fetch implementation should handle it (e.g. whatwg-fetch).

Thank you @elvinas-engagecraft and @Anitorious, will have this patched, tested, and released soon.

I believe I'm running into a similar issue when attempting to post to a json:api endpoint, e.g.:

      api.post('/entity', {
        headers: {
          'content-type': 'application/vnd.api+json',
        },
        body: JSON.stringify(entityData),
      });

Yields:

    ...
    "659": "i",
   ...(truncated to the first 10000 characters)

Submitted a PR. This probably exposes a hole in test coverage, as well?

This is actually resolved as of v3.1.2, not v3.1.1. See 45f4614.
