Here runtime\mbitmap.go
in function findObject
I changed this statement

		// The following ensures that we are rigorous about what data
		// structures hold valid pointers.
		if debug.invalidptr != 0 {
			badPointer(s, p, refBase, refOff)
		}

to this

		// The following ensures that we are rigorous about what data
		// structures hold valid pointers.
		if debug.invalidptr != 0 {
			return
			badPointer(s, p, refBase, refOff)
		}

and it works... I probably shouldn't leave it like this...

Hi, I was creating a client multiple times but I had to create it once and to use it. After I've done it like this error is gone.
