Adobe Sign is not sending the email

I'm able to successfully upload the document and initiate the signature request, receiving a confirmation with the agreement ID. However, it appears that the email containing the agreement is not being sent. Additionally, when attempting to access the document from the "canceled " section of my account, I encounter the following message:

"The document is not yet available or will have no pages to view."

I am using developer account and running  script for automation.

Has anyone experienced a similar issue before? Any insights or suggestions would be greatly appreciated.

Thank you in advance for your help.
