That's weird, the decodePayload() method should always be called with a String...

It might be fixed by https://github.com/socketio/engine.io-client/commit/ec3f677e9240a8947b6a12e15e3fd77e9bbb51d5 though.

@darrachequesne , new exception in 3.0.1 release

Uncaught DOMException: Failed to read the 'responseText' property from 'XMLHttpRequest': The value is only accessible if the object's 'responseType' is '' or 'text' (was 'arraybuffer').

Any workaround for this issue? Currently we are developing a new site, so i could downgrade. For now it should be fine to downgrade, but maybe someone has a better idea?
