If you encounter a sitemap error while moving a PowerApps solution from a Dev/QA environment to a production environment, here’s a simple fix:

  1. Open your PowerApps solution in the source environment.
  2. Look for the “Sitemap” section on the left side of the solution.
  3. Identify and remove any unnecessary sitemaps from this section.
  4. Export the updated solution.
  5. Import this solution into the production environment to resolve the error.

Note that this is just one approach; there might be other solutions available.
