Hi @Naseef Mohammed Ansaf Mohammed Thowfeek
Greetings & Welcome to Microsoft Q&A forum! Thanks for posting your query!
The error message you are encountering, "Workspace request validation failed," typically indicates that there is an issue with the parameters or configurations specified for the workspace deployment. To troubleshoot this issue, consider the following steps:
- Check Deployment Operations - The error message recommends that you list the deployment operations to get more details. This will show you a more granular view of each step in the deployment process, highlighting exactly where the failure occurred.
- Review Request Parameters - Ensure that all parameters for creating the Synapse Analytics workspace are correct. Double-check the values for the workspace name, region, storage accounts, networking settings, etc.
- Permissions - Make sure that the account you're using to deploy the resources has sufficient permissions in the subscription and resource group.
- Check Azure Resource Limits - Sometimes, deployment failures can be due to hitting Azure resource limits (such as the maximum number of Synapse workspaces allowed per subscription). You can check the quota limits for your subscription.
