Adding Hybrid Connection with Azure CLI failed with slot parameter set

Question

Hello,

I'm trying to use Azure CLI command to add Hybrid Connection to the app service slot, but it failed with error:

The command failed with an unexpected error. Here is the traceback:
Unable to build a model: Unable to deserialize to object: type, AttributeError: 'str' object has no attribute 'get', DeserializationError: Unable to deserialize to object: type, AttributeError: 'str' object has no attribute 'get'

I'm using command copy-pasted from documentation:
az webapp hybrid-connection add -g MyResourceGroup -n MyWebapp --namespace [HybridConnectionNamespace] --hybrid-connection [HybridConnectionName] -s [slot]

https://learn.microsoft.com/en-us/cli/azure/webapp/hybrid-connection?view=azure-cli-latest#az_webapp_hybrid_connection_add-examples

Is there a possibility that I'm using it wrongly?

@Jagoda Thanks for reaching out and apologies for not getting back sooner here.

This bug was reported to the Azure CLI team a couple weeks ago: https://github.com/Azure/azure-cli/issues/18406
This issue has now been fixed as part of version 2.26.0 and released on July 06, 2021.

Please upgrade your Azure CLI installation to the current latest version ( 2.26.1 ) and give it another try.

Hope this helps. Do let us know if you still run into issues.
