I'm trying to load and run a very simple eBPF program and I am faced with an obscure error code (524). The program that I'm trying to load is very simple:

#include "vmlinux.h"
#include 

SEC("tracepoint/syscalls/sys_exit_open")
int tracepoint__syscalls__sys_exit_open(struct trace_event_raw_sys_exit* ctx)
{
    return 0;
}

char LICENSE[] SEC("license") = "GPL";

The eBPF program is loaded using the generated skeleton:

int main (int argc, char *argv[]) {
        struct __sk_buff skb = {0};
        struct hello_bpf *skel;
        int prog_fd, err = 0;

        // define our BPF_PROG_RUN options with our mock data.
        struct bpf_test_run_opts opts = {
                // required, or else bpf_prog_test_run_opts will fail
                .sz = sizeof(struct bpf_test_run_opts),
                // ctx is an skb in this case
                .ctx_in = &skb,
                .ctx_size_in = sizeof(skb)
        };

        // load our fib lookup test program into the Kernel and return our
        // skeleton handle to it.
        skel = hello_bpf__open_and_load();
        if (!skel) {
                printf("[error]: failed to open and load skeleton: %d\n", err);
                return -1;
        }

        // get the prog_fd from the skeleton, and run our test.
        prog_fd = bpf_program__fd(skel->progs.tracepoint__syscalls__sys_exit_open);
        err = bpf_prog_test_run_opts(prog_fd, &opts);
        if (err != 0) {
                printf("[error]: bpf test run failed: %d\n", err); // -1
                perror("bpf_prog_test_run_opts"); // bpf_prog_test_run_opts: Unknown error 524
                return -2;
        }

        return 0;
}

When trying to run the compiled binary I'm faced with the error: "Unknown error 524". Can anybody point me in the right direction?
