InviteByEmail $message['body'] should be an (array)

We're planning to release the new version 2.0.x so let's move this for the new version

Hey @kalpaitch, thanks for you fix. I've try to apply that on 2.0.x, so follow the new patch

I was trying but is returning this error:

Do you have some idea about what can be?

I believe this issue would be resolved by using the code in #3275572: Implement hook_mail().

I can create a patch for the 2.0.x branch, if you like.

Ah amazing @dale42.

Yeaaah, If you can, please

I can commit that for us o/

Attached is patch file invite-hook-mail-upd-3227581-9.patch with the changes from #3275572.

I tested with the native Drupal mailer and Swift mailer.

I applied and tested. It really works well

Thanks a lot for your contribution @dale42 and @kalpaitch

Committed to the dev branch.

Thanks a lot
