Message content could not be generated
I use SendGrid for emails and in-app notifications. I have several workflows, but sometimes when I send notifications, I encounter an error: "Message content could not be generated." When I check the details, I find that the "error" field is empty. When I try triggering the email again using a curl request, I see that the email is sent successfully. This error occurs intermittently, at different times of the day and with different emails. I wrote to the chat but i am left with a seen for many times. Also i issued a bug in github but still nothing.
