I looked for a way to catch it, didn’t have any luck, but I think having a notice would be a great addition. I’m glad this helps. The plugin is great btw!
Simple, but not obvious. Glad it worked.
I’m not sure if my issue is the same as yours, but I was receiving the same error message.
Check your options on the Hubspot form in the Hubspot editor, and double check that you don’t have it set to redirect to another page on submit. When I had this option set, I was getting the error. When I set it to just display a thank you message, I was all good.
