Check clang-formatting
Ubuntu clang-format version 11.0.0-2~ubuntu20.04.1
Some files were not formatted correctly according to the .clang-format file.
Please run clang-format version 10 or greater to fix the issue by using this bash command at the root of the repo:
find ./sdk \( -iname '*.hpp' -o -iname '*.cpp' \) ! -iname 'json.hpp' -exec clang-format -i {} \;

##[error]Bash exited with code '1'.

The issue has been fixed in #4673
