Systems Manager document issues.

AWS Systems Manager allows you to create, manage, and automate tasks on your AWS resources. If you're facing problems with Systems Manager documents, here are some common issues and troubleshooting steps:

1. Error Messages: Provide any error messages you're encountering. This can give clues about what might be going wrong.
2. Check Document Syntax: Ensure that the Systems Manager document is correctly written in JSON or YAML format. Even small syntax errors can cause issues.
3. Verify Document Permissions: Make sure that the IAM user or role executing the document has the necessary permissions to perform the specified actions.
4. Review Document Content: Double-check the content of the document. This includes the parameters, steps, and any references to other AWS services.
5. Document Execution Logs: Look at the execution logs for the document. This can provide more detailed information about what's happening during execution.
6. Check for Invalid Parameters: Ensure that the parameters passed to the document are valid and correctly formatted.
7. Document Version: Verify that you are using the correct version of the document. Sometimes, multiple versions of a document can exist.
8. Check for Resource Availability: Ensure that the AWS resources (e.g., EC2 instances) targeted by the document are available and in the correct state.
9. Review AWS Service Limits: Make sure you haven't exceeded any service limits related to Systems Manager or the services it interacts with.
10. AWS Systems Manager Agent (SSM Agent): Ensure that the SSM Agent is installed and running on the target instances. This agent facilitates communication between Systems Manager and your EC2 instances.
11. Monitor for Custom Logs: If you've included custom logs or scripts in your document, check those for errors.
12. AWS Forums and Support: If you're still stuck, consider posting on the AWS forums or contacting AWS support for specialized assistance.
