Solarlog Binding Returning nothing (Solarlog 50)

My Solarlog Binding retuns an empty String

11:02:58.192 [WARN ] [rlog.internal.handler.SolarLogHandler] - Parsing number failed. Returning nothing
java.lang.NumberFormatException: Character A is neither a decimal digit number, decimal point, nor "e" notation exponential mark.

Any Ideas?
I also tired to use the http binding, but it dosen’t show up any channels. Is there any way to debug. I turned on: TRACE but it only shows:
[inding.http.internal.HttpThingHandler] - Using the secure client for thing 'http:url:c5cb7904cd'

API is working. I can make the REST Request with Firefox and it shows the data.

That would be up to you to configure them, generic HTTP has no idea how to interpret random data.

May we see?

It’s possible the API format has changed.

The Query from the solarlog manual mentioned in the openhab binding document shows :
{„801“:{„170“:null}} Response: {{"QUERY IMPOSSIBLE 000"}}
but when i call:
{"780":null,"781":null} Response: {"780":2005,"781":2042} (current production + current consumption.

which Query is send from the binding?

Ok, so the DEBUG from solarlog binding is:

15:19:08.718 [DEBUG] [rlog.internal.handler.SolarLogHandler] - Running refresh cycle
15:19:08.719 [DEBUG] [rlog.internal.handler.SolarLogHandler] - Attempting to load data from http://192.168.2.97/getjp with parameter {"801":{"170":null}}
15:19:08.730 [WARN ] [rlog.internal.handler.SolarLogHandler] - Parsing number failed. Returning nothing
java.lang.NumberFormatException: Character A is neither a decimal digit number, decimal point, nor "e" notation exponential mark.
        at java.math.BigDecimal.<init>(BigDecimal.java:518) ~[?:?]

But Rest Api is showing some Content when send from Firefox for the same call:
"{\"801\":{\"170\":null}}"
