[APM][Entities] The APM service page not loading with logs service

[jennypavlova]

Summary

Once we enable the FF: (entityCentricExperience) we should be able to see a service coming from logs (without metrics present) in APM service overview.
Instead, the Overview page content is not loading:

Technical Details

Based on some testing I saw that probably a format change broke the page. This is what I see in the summary response:

This is used for the logic to decide if "logs" are present in the entity. This is the logic in the code. I would propose to refactor the logic: first check if the value is an array before we add it and then based on the value decide if we should add 'logs' (or the value we receive) in the array.

Testing

Another thing to test based on the conditions here check with different services from different sources (logs / APM)
Special case: Test with service coming from logs without any APM services in the env (only logs)

AC

• The APM service overview should load with different services coming from different sources (both logs and APM)
• The APM service overview should load with only services coming from logs (with entityCentricExperience on)
• The APM service overview should load with only services coming from APM (with entityCentricExperience on and off)
