Not able to connect the websocket data source

Grafana k6 Extensions
1

Hello,
I am using the golioth-websocket-datasource plugin (version 1.0.2) with Grafana (version 12.1.1). When I try to connect to my local WebSocket API at “ws://localhost:1845/ws/simple/prozelBMS/1”, I am unable to connect. Instead, I receive the following error:

**failed to read CustomSettings from the Query Request: error converting json.RawMessage to map[string]string

my api responce is as per the below**
{

"topic": "prozelBMS",

"partition": 1,

"offset": 818,

"value": {

    "PZ-DHL-BMS-B-BMS802-A": 0,

    "PZ-DHL-BMS-B-BMS802-V": 1284.6,

    "PZ-DHL-BMS-B-BMS802-W": 0,

    "timestamp": "2025-09-08T11:37:30.000Z"

},

"timestamp": 1757331451783

}

Did you found any solutions on this??

Did you find any solutions for this? In my case, everything was working fine until I changed the host. After that, this message started to appear. Now, even after switching back to the old host, I’m still having the same problem.

The solution is to use a different version of Grafana. I had the same issue, which occurred after Grafana was updated. I switched to another version — in my case, Grafana 11.1.2 — and that resolved the problem. I chose this specific version because I didn’t want to experiment with minor version changes; I just wanted to make sure I was using one that definitely works. However, you can try with other versions as well.
