Compiler panics after giving ``await` is only allowed inside `async` functions and blocks` error

[zeon256]

Code

Not exactly sure where the error is coming from. It happened in this commit. I am suspecting this line is the one causing it.

    fn get_traffic_flow(client: &C) -> LTAResult<Vec<String>> {
        client
            .build_req_with_skip::<TrafficFlowRawResp, _>(
                &concat_string!(client.base_url(), "/TrafficFlow"),
                None,
            )
            .await
    }

I believe this is a duplicate of #121096, and is already fixed on master (by #121664), so I'll close this issue as such. Feel free to reopen if the next nightly somehow doesn't fix this, but I checked with that PR's artifacts and it didn't reproduce.

Thanks for opening an issue!
