It doesn't seem to be resolving properly it's internal dependencies when tests run :(

Error appearing:

    Cannot find module '@esm2cjs/fetch-blob/file.js' from 'packages/directline-connector/node_modules/@esm2cjs/formdata-polyfill/cjs/index.js'

Instead of @esm2cjs/fetch-blob/file.js should be looking at @esm2cjs/fetch-blob/cjs/file.js
