I get this error some times when use getDevicePowerState

g: FetchError: invalid json response body at https://eu-api.coolkit.cc:8080/api/user/device/status?deviceid=10007df37d&appid=YzfeftUVcZ6twZw1OoVKPRFYTrGEg01Q&nonce=uf1lhtn&ts=1604043174&version=8&params=switch%7Cswitches reason: Unexpected token < in JSON at position 0

I add this code to mixins/makeRequest.js after line 42, because the API ramdomly answer with a crazy html shop code.

Maybe is a bad solution but works for me.

let request = await fetch(requestUrl, payload);
let contentType = request.headers.get("content-type");
    
while(!(contentType && contentType.indexOf("application/json") !== -1)) {
    request = await fetch(requestUrl, payload);
    contentType = request.headers.get("content-type");
}

I’m very happy it work!! Maybe the fix must be included in the oficial code. How?

I'm writing here because I think my problem could fit in here.

I have the following error:

"FetchError: invalid json response body at https://eu-api.coolkit.cc:8080/api/user/login reason: Unexpected token < in JSON at position 0"

I have Node-Red running via IOBroker.
I installed the ewelink-contrib via the palette management of Node-Red.

Unfortunately, I can only get about 6 power state nodes online. So when I try to use 20 nodes from ewelink, only about 6 remain online. The rest are offline, with the error message I inserted above.

It is also not clear which are online and offline, this changes after small changes and a deploy. There are no wrong settings and all hardware devices are actually reachable.

I can't find this file.
mixins/makeRequest.js

I am using FileZilla and have searched the entire Pi. Can anyone help me? Where and what I need to change.

Thanks a lot
