code 400 sendgrid

Hi,

When I send a test email, I receive:

Code: 400, Message: Bad Request, Body: {"errors":[{"message":"Unless a valid template_id is provided, the content parameter is required. There must be at least one defined content block. We typically suggest both text/plain and text/html blocks are included, but only one block is required.","field":"content","help":"https://sendgrid.com/docs/API_Reference/Web_API_v3/Mail/errors.html#message.content"}]}

I think when somebody erase sendgrid api key and create another, and replace in the plugin, it crashes.

I thing it’s an old problem. I have another topic with the same problem. I don’t know how I solved in the past.

Best regards.
