email sign up fails with error: "FAILED_TO_CREATE_USER"

Hi community, I have this issue where I constantly get the error FAILED_TO_CREATE_USER with an error code 422, when i try to sign up a user via email. I have added a screenshot of the network error logs. I couldn't figure out what I am doing wrong. Did anyone experience something similar and can help? My setup is following: - React.js w Vite - Hono.js w trpc routes - DrizzleORM
