Sprout Forms + Email - internal server error

Question

Sprout Forms 2.5.1 Sprout Email 3.0.3

I am getting the error "Internal Server Error - Illegal string offset 'template'"

I have updated the template file to use email variable instead of entry for the html and text content respectively.

Stack trace:

Answer 1

Although the Sprout Email docs state it is preferable to use shorthand syntax for variables in notifications, I found this to not be the case for the Notification subject line.

So using {companyName} in the subject would cause the issue shown above.

{{object.companyName}} fixes this.
