Webhook Header Contains charset in Content-Type

[people person]

Hello,

When code changes are pushed to my Bitbucket repos, I am having it hit a webhook on an external tool. The external tool is expecting the content-type of the header in the request to exactly match "application/json" but instead Bitbucket is sending "application/json; charset=utf-8" instead.

Is there a way to modify the content-type in the Header?

X-Request-Id: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Content-Type: application/json; charset=utf-8
X-Event-Key: repo:refs_changed

HTTP Status: 400

{"err": "This plugin only supports json content. Received: application/json; charset=UTF-8"}

Thanks in advance!
