Error tx index check

[Arnaud49750]

Hello,
Thanks for the tool.
I try to adapt the explorer on a fork of bitcoin. I'm not a developer and do that for "fun" and I try to find by myself.
But now I can't. I saw the #300 but it's look like doesn't work for me. I try to explain:
I've got the first message: btcexp:app txindex check: trying getindexinfo and btcexp:app txindex check: error in rpc getindexinfo; will try again in 900000ms and btcexp:error Error o2328ryw8wsde. That's all.
Node v18.16, Bitcoin core<v17. I'm connected, I can see ATH difficulty
No txindex check: getindexinfo unavailable, trying txid lookup or txindex check: unavailable
The first error message is :btcexp:error Unable to parse node version string
Could you help me ? Thanks
