OpenSearch serverless create error

The error message is quite generic and annoying to troubleshoot. I suggest doing these as these are the most common issues:

• Check the OpenSearch logs to see if there are any error messages or exceptions that provide more information about the issue. This could help you identify the root cause of the problem.
• Permission issues: Make sure that you have the correct permissions to create a collection. You may need to check the access control policies for the OpenSearch service and IAM users or roles to see if they have the necessary permissions.
• Incorrect input parameters: Double-check that the input parameters you provided are correct. The name of the collection, the index and type names should be valid and should not contain any special characters or spaces.
• Resource limitations: You might have reached the resource limits of the OpenSearch cluster or the individual node where you are trying to create the collection. In this case, you may need to increase the available resources or reduce the size of the collection.
• Connectivity issues: Ensure that there are no network connectivity issues between the client and the OpenSearch cluster. You may need to check the network configuration and security groups to ensure they are correctly configured.

If none of these troubleshooting steps work, you may need to try to raise an issue at https://github.com/opensearch-project
