I am getting a string as output example below,

"errors": "Report with Report Name production already exists[Ljava.lang.StackTraceElement;@8cb9814"

I need a regex to identify a pattern to eradicate [Ljava.lang.StackTraceElement;@8cb9814 it from output string. So that the output string looks like

"errors": "Report with Report Name production already exists."

Below is the code I am trying to complete.

let x = `"errors": "Report with Report Name production already exists[Ljava.lang.StackTraceElement;@8cb9814"`;

console.log(x.replace("Some Pattern", ''));

Use `x = x.replace(/\[Ljava\..+$/, '');` – anubhava Aug 07 '19 at 10:46
It's actually not that hard really. Have you tried doing it yourself? You just need to grab the relevant part and discard the rest. You can try using the "[" as the identifier if the message format is going to be consistent. – The Doctor Aug 07 '19 at 10:47
`s.substring(0, s.indexOf('[Ljava'))+'"'` – Wiktor Stribiżew Aug 07 '19 at 10:50
