error executing template %q: %v

Error message

error executing template %q: %v

What it means

A previously parsed template failed at execution/rendering time in templateResource.Open(). Parse-time syntax was fine, but evaluating the template against its context raised an error (e.g. calling a func that errors, or invalid value operations). The key in the message identifies which template failed.
