Some applications may not return any info contributors, resulting in an empty page.
This can be caused by a couple of reasons:
The info endpoint is not exposed, this can be solved by exposing info or adding info to an existing exposure using the management.endpoints.web.exposure.include property.
Additionally, you may also generate the build information for your application, which will enable the BuildInfoContributor and pass the git information to your application, which will enable the GitInfoContributor. Instructions on how to do that can be found here
