Build Error: Error: Sandbox Exec Error



  • When doing an Android Release Build on Monca LocalKit, the following error is occurring:

    • postBuild -
      Remove working directories…
      Build Error: Error: Sandbox Exec Error: [ Error: invalid data
      ]


  • Problem has been solved!!!

    The problem was that the project had a “google-services.json” file that was in the “UTF8 With BOM” format. I turned this file to “UTF8 Without BOM” and Build worked!
