Non EE receiver or subscriber

If the author instance tries to publish content to a public instance without a valid license, you will see the following in the log:

To resolve this issue, see the section on updating a key on the License page.

In some cases, your license is valid but you have different Magnolia versions running in the Author and Public instances.

In this scenario, check the value of the /server/filters/multipartRequest/@enabled parameter. It must be set to true.

In some circumstances, you may need to set the parameter to false, for example to get REST calls to work with attachments. If this applies to your case, use a bypass:

<sv:node xmlns:sv="" xmlns:xsi="" sv:name="skipRestCall">
  <sv:property sv:name="jcr:primaryType" sv:type="Name">
  <sv:property sv:name="class" sv:type="String">
  <sv:property sv:name="pattern" sv:type="String">
