  unknown field `bundle`, expected one of `$schema`, `package`, `tauri`, `build`, `plugins`
  found an unknown configuration field. This usually means that you are using a CLI version that is newer than `tauri-build` and is incompatible. Please try updating the Rust crates by running `cargo update` in the Tauri app folder.

```
Assistant: The error message you are encountering indicates that there is a problem with a custom build command in your Tauri project, specifically related to an unknown configuration field in your `tauri.conf.json` file. Let's break down the key parts of the error message:

1. **Custom Build Command Failure**:
   - The error message mentions a failure to run a custom build command for the `rendavi` package. This generally means that during the build process, a script (in this case, a Rust build script located at `build-script-build`) encountered an error.

2. **Unknown Configuration Field**:
   - The specific issue is related to an "unknown field `bundle`, expected one of `$schema`, `package`, `tauri`, `build`, `plugins`". This suggests that in your `tauri.conf.json` file, there is a field named `bundle` which is not recognized by the version of the `tauri-build` crate you are using.

3. **Version Mismatch**:
   - The suggestion from the error message is that there might be a version mismatch between the Tauri CLI and the `tauri-build` crate used in your project. Specifically, it indicates that you could be using a newer version of the Tauri CLI that expects different configuration options from what your `tauri-build` crate version supports.

4. **Recommended Solution**:
   - The error message suggests running `cargo update` in the Tauri app folder. This command updates the Rust crates in your project to their latest compatible versions, which could resolve the mismatch by updating `tauri-build` to a version that recognizes the `bundle` field in your configuration file.

### Steps to Resolve the Error:

1. **Run Cargo Update**:
   - Open a terminal and navigate to the root directory of your Tauri project.
   - Execute the command: `cargo update`. This will update your dependencies to the latest versions specified by your `Cargo.toml` file.

2. **Verify the Configuration**:
   - Double-check your `tauri.conf.json` file to ensure that it adheres to the expected structure and fields for the versions of Tauri CLI and `tauri-build` you are using.

3. **Check Compatibility**:
   - If `cargo update` does not solve the problem, consider checking the version of the Tauri CLI you have installed and ensuring it matches with the Tauri dependencies in your `Cargo.toml`. You may need to adjust versions to maintain compatibility.

4. **Consult Documentation**:
   - If issues persist, refer to the Tauri documentation or release notes for changes between versions that might affect configuration file structure.

By following these steps, you should be able to resolve the build error caused by the configuration mismatch.
