I have just set up Sendgrid in a canvas template (ver 3.6.2); everything seems regularly set up, but when I send an email I receive the following error:
Plugin action Send basic email error:
TypeError: Cannot read property ‘slice’ of null
at eval (eval at build_function (/var/task/index.js:72:21), :39:15)
at run_fn (/var/task/u.js:594:18)
Take in consideration that his happens only when I try to send a “basic email”, but it does not happen when sending a “custom email”.
Can you tell me why this happens?
