Projects Dashboard and Projects summary show "This project is Empty" while Issues are populated

We have a custom plugin created that works on LTS versions of SonarQube. In SonarQube 7.5 version that is used by our users, after the project analysis is complete, the Projects Dashboard and Project Summary Dashboard show “This project is empty”. When the project is clicked, the same message is shown on the project summary page. However, the Issues and their corresponding tags are populated correctly.

A couple of things to note

  1. On the same SonarQube instance, if a Java project is run, the project summary is populated
  2. The same plugin works well and shows the project summary details on a later version like 7.7, 7.8 and 7.9.6. However the Project is empty message shows on SonarQube versions 7.5 and 7.6.

Is there a fix that we can provide for SonarQube 7.5 (Community Edition Version 7.5 (build 20543)). We asked the user if they could upgrade to a later version 7.7 or above and they said that their Enterprise version is 7.5 and they cannot change just for a single plugin.

Any help or guidance is appreciated. Images as below

SonarQube v7.5 was released in December 2018 – almost 4 years ago. It is unmaintained, unpatched, and represents an operational and security risk to this customer. It is EOL and they need to upgrade to at least v8.9 LTS as soon as possible. There’s no other support that can be provided.

Thank you for your response. I understand that there cannot be any fix in SonarQube itself. Is there anything that we can do in the plugin to work around this issue. If the Java project results are showing, then there is probably some minor thing missing in a custom plugin framework. Let us know if there is anything we can do to help the customer in this scenario. We will let them know of your recommendation too.
