For example,`bundle-v1.0.0.tar.gz` or `./bundles/team-bundle.tar.gz` {% endhint %} In your Project folder, run the following command: ``` snyk iac test --rules=bundle.tar.gz ``` The configuration scan results now include issues from both the default Snyk rules and your custom rules. See [Understanding the IaC CLI test results](https://docs.snyk.io/developer-tools/snyk-cli/scan-and-maintain-projects-using-the-cli/snyk-cli-for-iac/understand-the-iac-cli-test-results). To troubleshoot a local custom rules bundle, enable debug logs by running the command with the `--d` options: ``` snyk iac test --rules=bundle.tar.gz -d ``` Some possible problems include: * Providing an incorrect path to the bundle or a path to a non-existent bundle. Ensure the path passed to the `--rules` option can be accessed from the current location. The error is ``` We were unable to extract the rules provided at: ./invalid/location/bundle.tar.gz ``` * Providing a corrupted or invalid bundle. Ensure you have generated your bundle by following the instructions in [Getting Started with the SDK](/scan-fix-and-prevent/scan-with-snyk/snyk-iac/current-iac-custom-rules/writing-rules-using-the-sdk.md). The error is ``` We were unable run the test. Please run the command again with the `-d` flag and contact support@snyk.io with the contents of the output. ``` If you have found a discrepancy that you cannot explain, [contact Snyk Support](https://support.snyk.io). --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.snyk.io/scan-fix-and-prevent/scan-with-snyk/snyk-iac/current-iac-custom-rules/use-iac-custom-rules-with-cli/use-a-local-iac-custom-rules-bundle.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
