I am able to repro the issue in Cloud Shell but not able to repro it on my local machine.

az synapse spark pool create --name testpool--workspace-name testsynapseworkspace --resource-group rg --spark-version 2.4 --node-count 4 --node-size Medium
Command group 'synapse' is in preview. It may be changed/removed in a future release.
validation error: Parameter 'BigDataPoolResourceInfo.node_count' failed to meet validation requirement.

It might related to code here: https://github.com/Azure/azure-cli-extensions/blob/master/src/synapse/azext_synapse/vendored_sdks/azure_mgmt_synapse/models/_models_py3.py#L317 . But I don't understand why the error is reported.

With --debug, I see the error is thrown from cli.azure.cli.core.util

cli.azure.cli.core.util : validation error: Parameter 'BigDataPoolResourceInfo.node_count' failed to meet validation requirement.
validation error: Parameter 'BigDataPoolResourceInfo.node_count' failed to meet validation requirement.

@idear1203 you may need to add type=int in _params.py for node_count to pass the validation in SDK model.

Thank you all for fixing the bug. I just created another one MicrosoftDocs/azure-docs#60927. Not sure really it is a bug in the code or docs issue. Just putting it here FYI. Thanks again!
