I’m trying to use a custom HTML template to send an outbound message (it’s an A/B test, not sure that matters) and when I click “Schedule and set live” I get the error message “Attribute json blocks for html blocks contains an invalid message template variable.”
I sent 10 Preview messages successfully to various email addresses for testing, and only encounter the error when I try to set the email live.
I built the email in Figma with the Emailify plugin. I have exported code before using the same programs and didn’t get this error but obviously this is a different email with different styling. I am clearly not a programmer (I know just enough to be dangerous) and I am comfortable making minor changes in HTML.
I have read the help desk article https://www.intercom.com/help/en/articles/245-creating-html-emails and I see the list of supported HTML blocks but am not sure how to search in my code for something *not* allowed.
Happy to share the full code with someone who can help.
