I have setup Discourse 2.7.12 and configured it to send emails via Mailgun. Even though the application is able to send test emails via the Administration panel, all the relevant email jobs fail at Sidekiq Any ideas what could be the error? Sidekiq example of error: Jobs::CriticalUserEmail {“type”=>“forgot_password”, “user_id”=>4, “email_token”=>“ca2fd58bd00511d21d04ca05da6239ad”, “current_site_id”=>“default” } Jobs::HandledExceptionWrapper: Wrapped ArgumentError: :arguments expected to be an Array of individual string args Stack trace information In the /logs i can see an error with title: Job exception: :arguments expected to be an Array of individual string args and stack trace:

I fixed it by setting the SMTP parameters to the Sidekiq as well In /opt/bitnami/scripts/discourse-env.sh these are exported DISCOURSE_SMTP_HOST DISCOURSE_SMTP_ADDRESS DISCOURSE_SMTP_PORT_NUMBER DISCOURSE_SMTP_USER DISCOURSE_SMTP_USER_NAME DISCOURSE_SMTP_PASSWORD But Sidekiq was expecting the parameters not to have the DISCOURSE_ prefix. So adding the following fixed the problem: export SMTP_HOST=“xxx” export SMTP_ADDRESS=“xx” export SMTP_PORT_NUMBER=“587” export SMTP_USER=“xxx” export SMTP_USER_NAME=“xxx” export SMTP_PASSWORD=“xxx”

I am getting this error while sending test email. I tried adding smtp details in sidekiq. Note: I have deployed this on k8s. I am on version 3.0.6
