[warning] We ge this error message for Elliptic\Curve\ShortCurve\Point

[imClement]

Hi,

We get this warning in the log :Return type of Elliptic\Curve\ShortCurve\Point::jsonSerialize() should either be compatible with JsonSerializable::jsonSerialize(): mixed, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /var/www/html/vendor/simplito/elliptic-php/lib/Curve/ShortCurve/Point.php on line 84

Did you solve this? I'm facing the same issue.
On my localhost it's running fine, but on the webserver I receive exactly the error from above when initializing the EC context: $ec = new Elliptic\EC('secp256k1');

ERROR: Return type of Elliptic\Curve\ShortCurve\Point::jsonSerialize() should either be compatible with JsonSerializable::jsonSerialize(): mixed, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice on line 84 in file /home/.sites/.../.../.../../../.../vendor/simplito/elliptic-php/lib/Curve/ShortCurve/Point.php.

Hm, have you tried to look at https://github.com/simplito/elliptic-php? are there any solutions there?

I looked there but this was the only spot I found where the issue was at least mentioned.
Anyway I found the reason being the PHP version I used on the Webserver. To solve this issue you can either downgrade to 8.0.* or use the #[\ReturnTypeWillChange] attribute as suggested in the error message

Can you make a PR for this? happy to merge it 👍
