covr::codecov() fails on GitHub Actions CI

[yutannihilation]

covr::codecov() fails on ggplot2's repo with the following error. Anyone experienced this issue?

Error in curl::curl_fetch_memory(url, handle = handle) : 
  HTTP/2 stream 0 was not closed cleanly: PROTOCOL_ERROR (err 1)
Calls: <Anonymous> ... request_fetch -> request_fetch.write_memory -> <Anonymous>
Execution halted
##[error]Process completed with exit code 1.

(https://github.com/tidyverse/ggplot2/runs/509138337?check_suite_focus=true#step:13:14)

As this check seems work on other repo, and the same check works fine on Travis CI, I expect this is an issue specific to the combination of GitHub Actions and ggplot2.

This was due to an issue with HTTP 2 and macOS, now resolved in covr (https://github.com/r-lib/covr/commit/cc710804aeff6f337777465bf902914197c0b713)
