Issue

Projects created with Mendix Studio Pro and stored on drives other than C: may encounter errors like the one below when running a native mobile profile. Specifically, developers may receive Metro bundler errors indicating that essential files cannot be resolved or hashed correctly, such as failure to obtain the SHA-1 for native.js.

[Output] ERROR Error: Failed to get the SHA-1 for: D:\C:\Program Files\Mendix\10.24.1.74050\modeler\tools\node\node_modules\mendix\native.js.
[Output] Potential causes:
[Output] 1) The file is not watched. Ensure it is under the configured `projectRoot` or `watchFolders`.
[Output] 2) Check `blockList` in your metro.config.js and make sure it isn't excluding the file path.
[Output] 3) The file may have been deleted since it was resolved - try refreshing your app.
[Output] 4) Otherwise, this is a bug in Metro or the configured resolver - please report it.

Environment

Studio Pro (all versions)

Cause

This issue is that Mendix Studio Pro only supports running native mobile projects from the C: drive. When a project is stored on a different drive, like D:, the Metro bundler used for building native apps cannot correctly resolve file paths or calculate SHA-1 hashes, leading to bundling errors.

Solution / Workaround

To resolve the issue with native mobile app bundling in Mendix Studio Pro, the project must be saved on the C: drive. Moving the entire project directory from any other drive (e.g., D:) to C: ensures that the Metro bundler can correctly locate and process all necessary files during runtime. This configuration aligns with Mendix’s current supported setup for native development.
