Issue with Whatsapp input data (whatsapp+Gmail)

Im trying to set up a zapp that sends me a whatsapp message when a specific sendor/email address sends me a gmail email. When testing the action an error comes.


this is what the troubleshoot advice says:
 

The error message "(#100) Invalid parameter" typically indicates that one or more of the parameters being sent to the WhatsApp API are incorrect or not formatted as expected. In your case, the issue might be with the name field in the input data, which is constructed using dynamic data from the previous step. The placeholders {{287730198__from__name}}{{287730198__date}}, and {{287730198__body_plain}} need to be correctly mapped to the output fields from the Google Mail step. Ensure that these placeholders are correctly pulling the expected data. You can verify this by checking the output of the previous step and ensuring that each placeholder corresponds to a valid field.

To resolve this, go to the Zap editor and check the "send_message" step. Make sure that each dynamic field is correctly mapped to the corresponding data from the previous step. You can use the "Test & Review" feature in Zapier to see the actual data being passed through each step, which can help you identify any mismatches or missing data. Additionally, ensure that the link_to_reply field is a valid URL, as any invalid URL could also trigger an error. Once you've verified and corrected the mappings, test the Zap again to see if the issue is resolved.

That sort of error can occur when a message has more than 1024 characters. Our WhatsApp Notifications error: (#100) Invalid parameter guide has some ideas on how to fix that.

Can you take a look and let us know if the any of the potential fixes outlined in the guide help to resolve things?
