Tools available to diagnose solutions
There are two tools available for diagnosing solutions in Power Apps.
Object checker
Object checker and solution checker are similar and share much of the same infrastructure. However, object checker runs live diagnostics on the database and can analyze issues based on the metadata and layering of a given solution object - regardless of which solution(s) the object is in. Therefore, object checker is better suited for troubleshooting application lifecycle (ALM) related issues in test and production environments.

Solution checker
Solution checker runs offline analysis on a single solution file. Solution checker requires the solution be exported before you can run a solution diagnostic. Solution checker is best suited for development environments or analyzing a solution prior to committing it to a source control repository.
