Gin SetMode not Passing Value to Function, Cause Panic Error On Minikube/Microk8s about gin HOT 4 OPEN

The default is gin.DebugMode, which can be manually specified
My side is normal, later I will test this situation in version 1.22.5

package main

import "github.com/gin-gonic/gin"

func main()  {
    gin.SetMode(gin.DebugMode)
    r := gin.Default()
	r.GET("/", func(c *gin.Context) {
        c.JSON(200,gin.H{"msg":"ok"})
    })
	r.Run(":9000")
}

Your code seems to have been modified again, and you need to check if the source code of the gin has been modified again

hi RedCrazyGhost, thank for reply. in common linux, or windows or docker container, when I try run go gin with my code above, its normal work with no problem, but I try on kubernetes in microk8s and minikube its error happen. I even try enter to the exec on pods and run from there, but still error, I also debug on gin SetMode function for see what happen, and I found param not pass to the function.

maybe here is wrong, because you set a wrong global variable GIN_MODE
