I tried below function, however I couldn't get it though it. please anybody have solution?

var n = error.includes("registered");

You used the incorrect variable to get your expected result. Try to change error to message. var n = message.includes("registered"); — Jonnel VeXuZ Dorotan

your string name is 'message' but you're searching your word in a string named error, your first real problem is here — Axel Moriceau

You are trying to search for "registered" in a string called error but there isn't try this:

message =  'User error fabric-ca request register failed with errors [[{"code":0,"message":"Registration of \'yandgsub15\' failed: Identity \'yandgsub15\' is already registered"}]]' }

var n = message.includes("registered");

I think you just don't search on the good variable

In your example you're trying to search "registered" on error and not on message

The code below is working

message = 'User error fabric-ca request register failed with errors [[{"code":0,"message":"Registration of \'yandgsub15\' failed: Identity \'yandgsub15\' is already registered"}]]' 

var n = message.includes('registered')

console.log(n) // true
