had a secret with character '/'

for example git push https://username:foo/[email protected]

This character needs to be escaped/encoded: https://stackoverflow.com/a/59284165

so it becomes git push https://username:foo%[email protected]

fixed it by encoding the character manually and storing that as a secret. But should be very simple to automate. If you point me as to the where I could submit a PR for a simple search&replace (although tbh there's probably some better Java native URL encoder that needs to be called just before running the action)
