@gabrielmfern I accidentally made the repository private. I changed it to public so please check.

I've run into similar issue, but it seems to be related to prettier being very standards compliant. My exception shows:

SyntaxError: Unexpected closing tag "td". It may happen when the tag has already been closed 
by another tag. For more info see

It was working properly with @react-email/components at version 0.0.19 and stopped working after upgrade to 0.0.31.

I've managed to narrow it down to version 0.0.29 in which the issue started to appear. This components version uses @react-email/[email protected] which depends on [email protected].

Can confirm that this is indeed an issue with the pretty flag. When using the pretty flag, a TypeError is dumped to the console:

Same issue here with Cannot read properties of undefined . Also reported here https://github.com/resend/react-email/pull/1777#issuecomment-2539465482

Tried it out on the reproduction, and it seems to have been fixed as of the latest versions. Particularly after @react-email/[email protected]/@react-email/[email protected]
