I am using this pkg https://github.com/Danny-Dasilva/CycleTLS?tab=readme-ov-file#example-cycletls-request-for-golang to make a HTTP request and this package allows you to pass custom FingerPrint.

It seems FingerPrint generated by gospider007/fp is wrong as it gives the TLS error

Get "https://www.funfun.tools": conn.Handshake() error for tls 1.3 (please retry request): tls: CurvePreferences includes unsupported curve

But if I use the FP generated by this website https://ja3.zone/check it works good.

I used the same Browser to get the generated fingerprint

and JA3 generated by ja3.zone website is
771,4865-4866-4867-49195-49199-49196-49200-52393-52392-49171-49172-156-157-47-53,0-27-10-35-51-45-17513-5-65281-23-18-11-16-43-65037-13,4588-29-23-24,0

and also If I get the FP from this website https://browserleaks.com/tls that also works correctly

As you can see both are different

JSON file generated by Gospider: gospider_fp.json

I think it has to do with this issue salesforce/ja3#78
