openems's formula was built from an unstable upstream --HEAD.
This build failure is expected behaviour.
Do not create issues about this on Homebrew's GitHub repositories.
Any opened issues will be immediately closed without response.
Do not ask for help from Homebrew or its maintainers on social media.
You may ask for help in Homebrew's discussions but are unlikely to receive a response.
Try to figure out the problem yourself and submit a fix as a pull request.
We will review it but may or may not accept it.

Am I missing something? Would appreciate any help.
