	generateHash(e) {

		console.log(result)
		PayUBizSdk.hashGenerated(result);
	}

can any one help me how to understand this error what hash need

i try somthing like this also

generateHash(e) {
		var hashValue = sha512(e.hashString);
		var result = { [e.hashName]: hashValue };
		console.log(result)
		PayUBizSdk.hashGenerated(result);
}

generateHash(e) {
		var hashValue = sha512(e.hashString + this.state.merchantSalt);
		var result = { [e.hashName]: hashValue };
		console.log(result)
		PayUBizSdk.hashGenerated(result);
}

Salt and merchant key value in documentation and example is wrong

Here's my blog of the problem being resolved:

PayU Officials please do needful to update payu-non-seamless-react package and salt in docs
