Hi All,
i am trying to implement signature authentication scheme i am using below script from crypto module.

const apim = require('apim');
var crypto = require('crypto');

const key = new Buffer(context.get('private_key')); // i have stored PEM format private key in set variable.
var sign = crypto.createSign('rsa-sha256');
sign.update(signingString).sign(key, function(error, signature) {
if (error) {
console.error("sign error "+error);
} else {
console.log("signature with rsa-sha256 is "+signature.toString('base64'));
session.output.write(signature);
}
});

Getting below error

 Mon May 23 2022 20:57:10 [dsv][0x8580005c][crypto][error] apigw(dsv): tid(53743267)[request][10.251.117.103] gtid(982d310b628bf52603340ea3): *Fail to deserialize the key object* Mon May 23 2022 20:57:10 [dsv][0x8580005c][gatewayscript-user][error] apigw(dsv): tid(53743267)[request][10.251.117.103] gtid(982d310b628bf52603340ea3): sign error Error: *Fail to deserialize the key object*
