StartAutentication throwing 'Cannot read properties of undefined (reading 'replace') at base64URLStringToBuffer' about simplewebauthn

Hello @hapnan, your JSON Respons From server has the options for startRegistration() nested one level deep, off an "options" property in the JSON object. Can you try calling startRegistration() like this instead and see if that fixes your problem?

// Pass in the `options` property instead
attResp = await startRegistration(respon.options);

yes it is true that it was caused by the response server being nested one level deeper so I changed my response server to be more correct, thanks for helping, @MasterKale
