Solved after changing this

tryTraceReq function in dev_helpers.go

if len(waitList)>0 { p.browser.logger.Println(TraceTypeWaitRequests, p, waitList) }

setHelper function in page_eval.go

if p.helpers != nil && p.helpers[jsCtxID] != nil { p.helpers[jsCtxID][name] = fnID }

I've also encountered this bug. When I call page.MustWaitRequestIdle(), it results in a panic: assignment to entry in nil map.
