RTL channels and rate "Unknown Error"

[Globalebill]

@saubyk @ShahanaFarooqui @NicolasDorier

After upgrading to BTCPay1.11.6 for the resolution of bug Ride-The-Lightning/c-lightning-REST#199 the RTL front end is now giving errors on the Dashboard, Peers/Channels (peers list loads ok) and Rates pages as per the screen captures below, note: all other pages load with no errors

@Globalebill Can you share logs from c-lightning-REST and RTL? And data or error from Browser console (right click on browser -> Click on Inspect -> Go to Network tab -> listpeerschannels Response tab)

@ShahanaFarooqui

List Channels response: {"message":"List Channels Error","error":"Unknown Error"}

RTL logs, docker logs generated_bitcoin_rtl_1, prior to upgrade and after:

listChannels endpoint is deprecated after CLN 23.02. RTL should call listPeerChannels instead.

As per you last issue, you are on:
saubyk/c-lightning-rest:0.10.6
btcpayserver/lightning:v23.08
shahanafarooqui/rtl:0.14.0

But can you please confirm it in the UI also, like below:

[Globalebill]

versions:
shahanafarooqui/rtl:0.14.0
btcpayserver/bitcoin:25.0
saubyk/c-lightning-rest:0.10.6
btcpayserver/lightning:v23.08

btcpay 1.11.6 upgraded from 1.11.5

@Globalebill Thank you for raising the issue. It occurred due to Core lightning's version prefix (basedon) which has been prefixed by BTCPayServer. RTL expected the version to be starting with v only. Updated the regex to filter all prefix and postfix.

The fix will be released with v0.14.1 (hopefully this weekend). Closing the issue now.
