libbpf-tools errors:invalid access to map value, value_size=43 off=0 size=0 R1 min value is outside of the allowed memory range

[Jimskns]

In my original bpf code, I try to hook the sched_wakeup tracepoint,like this:

SEC("tp_btf/sched_wakeup")
int BPF_PROG(sched_wakeup, struct task_struct *p)
{
	u32 flags = BPF_CORE_READ(p, flags);
	u64 ts = bpf_ktime_get_ns();
	struct piddata* piddatap;
	struct piddata new_piddata = {};
	int ret = 0;
	if (allow_record(flags) && record_launch()) {
		u32 pid = p->pid;
		piddatap = bpf_map_lookup_elem(&start, &pid);
		if (!piddatap) {
			piddatap = &new_piddata;
			piddatap->pid = pid;
			piddatap->blocked_type = 0;
		}
		piddatap->runnable_start_ts = bpf_ktime_get_ns();
		bpf_printk("wakeup pid:%u runnable_start_ts:%llu\n", pid, piddatap->runnable_start_ts);
		ret = bpf_map_update_elem(&start, &pid, piddatap, 0);
	}
	return ret;
}

It works fine. However, when I replace the bpf_printk with bpf_trace_printk

bpf_trace_printk("wakeup pid:%u runnable_start_ts:%llu\n", pid, piddatap->runnable_start_ts);

,I got this error:

Could you help me please?
