mails failing to deliver when I send Amazon SES emails using the SendTemplatedEmail operation (Attribute 'vehicle' is not present in the rendering data)

Our team is facing issues with dynamic templates on production with SES after successfully submitting a queue. Webhook returning error "failure":{"errorMessage":"Attribute 'vehicle' is not present in the rendering data." even the attribute and value is there.

Template data you can find from "templateName":"Email_13122022_163112_c65a93f9-80e4-4cb6-8616-5370445fc5f7_8120"

Given below from the sending queue two types of data. Please check and provide the resolution of this issue.

1. It has the value "34344343443434" with the "vehicle" attribute.
