Failure on /api/v1/sessions/21/lrs/activities/state

[mogadanez]

I did setup catapult with cloud lrs.io

more or less working but I have strange issue in with call to GET /api/v1/sessions/21/lrs/activities/state

Added few console.logs at cts/service/plugins/routes/v1/sessions.js

                            if (req.method === "get" && req.params.resource === "activities/state") {
                                if (req.query.stateId === "LMS.LaunchData") {
                                    console.log(uri)
                                    console.log(rawProxyResponsePayload.toString())

on package initialize I'm getting:

But strange thing is - if I do copy as CURL and repeat it from postman - it works fine and show:

hm... interesting. seems my browser added header Accept-Encoding: gzip, deflate, br and it fail with it.

@mogadanez your ticket helped me as i was banging my head for hours on this as well!! What i ended up doing was adding the code below to the lrs.js file! delete options.headers["accept-encoding"];
