Hey, does somebody know, can regexp fail only because of

the big length of input string (my string is a little bigger than 800k symbols)?
str := "somestring \"text\":[`somestring`,] somestring"
reg := regexp.MustCompile("\"text\":\\[`(.*?)`,\\]")
match := reg.FindStringSubmatch(sbody)
fmt.Println(match[1])
This example works correctly, but when I change str with real string with 800k symbols, i have this error
goroutine 1 [running]:
main.main()
Path/to/directory/main.go:24 +0x19f

Process finished with the exit code 2
If i am wrong, what can be cause of this error?

Lesson learned to never just use a slice without length checking it first :P

Instead of printing a single element (match[1]), try printing the whole thing fmt.Printf("%v\n", match ). match could be empty or have only 1 element.
