We are pleased to announce a new security update aimed at providing enhanced protection against potential phishing attacks or malicious activities. As part of this update, processing JavaScript files will result in an “invalidContentType” validation error.

This change has been implemented to safeguard the security of our platform and prevent the distribution of potentially malicious files through our CDN.

For our customers who require continued functionality for their content operations and have a valid use case, we have established a allow-list. If you have any questions or would like to be considered for inclusion on this list, please do not hesitate to reach out to our support team at support@contentful.com.
