Hey @rickychilcott. Thanks for this PR. We're trying to make all callable blocks around Avo adhere to execute from an isolated place. More explanations about that here.

Would you be willing to refactor this PR to reflect that using the changes in this PR? Specifically, this line here is what I'm talking about.
