Block Error, Preview Fails

[BrandiCap]

When I add the ConvertFlow CTA block I receive this error:

There are multiple sites experiencing this error, all of which are using version 0.4.1 of the plugin. The error does not allow you to preview or even select a CTA. CTAs that have been added prior to this issue still display the error, but they show up fine on the front end of sites.

@dws122 @JiveDig Is there a status update on this - to my knowledge, it's still an issue.

@JiveDig @dws122 a new wrinkle here discovered as I was adding CTAs to a client site today. I have been getting around the above error by adding CTAs using the shortcode [convertflow_cta id="12345"] (replacing the numbers here with the CTA id) but today the only way they would display was when I refreshed the API on the backend of the site...thought it worth mentioning.
