Hello everyone. Is anyone familiar with the error "A template that includes another one cannot include content outside of twig blocks", but only when the survey is made active? Our non-active previews of the survey are fine. We activate the survey with every possible option tested, and it continues to read as a 500 server error with this description. We manually sifted through line by line to compare the code of the original vanilla theme with the code that we updated in our extended theme. Everything appears to be exactly in place when it comes to blocks and includes. Could this be a bug? Is there something else we could check to diagnose? Thanks for your help!

I found the issue. It was a tiny trivial html comment in an area OUTSIDE OF A BLOCK in a twig that didnt like html comments. As soon as I typed the question in my post, I reheard the error in a diff context and it made sense. Keeping this here in case it helps others. Thanks
