I trying to use regex in golang.
This i was expecting the regex below to return false, However its returing true. What am i doing wrong with the regex. I tested this regex on https://regex101.com/ it should not return true. But in golang it returns true

My goal was to find a regex for /v2/echo/{asd}/te-st?start_date=2024-01-01
I created this ^(?:/[a-zA-Z0-9_{}?=-]+)+ it works fine on regex101

package main

import (
    "fmt"
    "regexp"
)

func main() {
    regExp, err := regexp.Compile("^(?:\/[a-z]+)+")
    if err != nil {
        panic(err)
    }
    fmt.Println(regExp.MatchString("/v2/echo/{asd}/te-st?start_date=2024-01-01"))
}

I was expecting fmt.Println(regExp.MatchString("/v2/echo/{asd}/te-st?start_date=2024-01-01")) to return false
