Answer 1

The error management of the email plugin is not good, we have to change it!

This error is probably provided by this code line

To got the correct error, I suggest you to add a console.log of the err in your strapi-provider-email-sendgrid node_module directly.

I know it's not good to do that but it will be the only way to know the error that you have.

Answer 2

I faced similar issues with the AWS SES email provider from Strapi, so I'll leave my resolution here in case someone googles their way into this question in the future.

That error message is actually thrown by the Sendgrid Strapi email provider in line 58 (https://github.com/strapi/strapi/blob/dae9cfa415881f17ebb95d9ea3887c6a0ae0dca6/packages/strapi-provider-email-sendgrid/lib/index.js#L58).

There's a catch that will swallow exceptions thrown by the Sendgrid library and throw instead this generic message. Here are your options to figure out what the actual error is:

1. Debug the provider by attaching to the running NodeJS process
2. Add some console.log statements to the node_modules/strapi-provider-email-sendgrid/lib/index.js file inside the catch and inspect your standard output
3. Modify the call to reject inside the catch to return the actual error.message string. This might require looking into how Strapi will handle errors thrown inside controllers to make sure it doesn't end up getting lost in the I18N midlleware or other extension points.

I had the same problem with strapi/sendgrid. The problem was the fact that the sender was not a verified email in sendgrid.

Step to fix:

• I looked for : id: 'Auth.form.error.email.invalid' in my node_modules.

• Then, I logged the error

   sendgrid.send(msg, function(err) {
     if (err) {
      console.log(err.response.body.errors)     
      reject([{ messages: [{ id: 'Auth.form.error.email.invalid' }] }]);
     } else {
       resolve();
   } 

• I had the following message inside the error : "The from address does not match a verified Sender Identity. Mail cannot be sent until this error is resolved. Visit https://sendgrid.com/docs/for-developers/sending-email/sender-identity/ to see the Sender Identity requirements"

• So, i went to sendgrid and verified my sender's emails. And it worked :)
