Issue with 'Send a Message' Module in WhatsApp

Hello Make Community,

I am encountering an issue with the ‘Send a Message’ module in WhatsApp Business Cloud. Despite the message being successfully sent and received by the recipient, I am still receiving the following error message:

“Validation failed for 1 parameter(s). - Missing value of required parameter ‘to’.”

I have tried various solutions to resolve this issue, but none have been successful so far. Here are the steps I have taken:

  • Verified that the recipient’s WhatsApp ID is correctly mapped.
  • Ensured that all required fields are filled in the module.
  • Double-checked the format and structure of the data being sent.

Despite these efforts, the error persists. I am seeking help from the community to fix this problem. Has anyone else experienced this issue or have any suggestions on how to resolve it?

Thank you in advance for your assistance!


Hi @Bart_off

Thanks for reaching out to the community. This error happens when the mapped variable in the module does not have any value.

So, please check if the input is passed properly in Whatsapp module.
