Pipefail doesn't work with pipes

When I run 

set -euo pipefail

then I run any command with pipes( | ). It throws an error.

#[error]Process completed with exit code 1.

 Here is the log.


If you can help me, it would be great! thank you!

The bash shell on GHA runs set -eo pipefail by default. You can find more information here:

It seems, actually it does not.
