Cant decompile Service Bus template exported from Azure Portal

[afscrome]

Bicep version Bicep CLI version 0.4.63 (7ebed03284)

Describe the bug After exporting the ARM json template from a service bus resource in the portal, I was unable to decompile it to bicep due to several errors about The property "location" is not allowed on objects of type ...

Not sure if this is a bug with the bicep decompiler / api spec not allowing this property, or with the azure template generation incorrectly including the location properties.

A selection of those errors are below

> az bicep decompile --file .\serviceBus.json 

C:\Temp\serviceBus.bicep(89,3) : Error BCP037: The property "location" is not allowed on objects of type "Microsoft.ServiceBus/namespaces/AuthorizationRules". Permissible properties include "dependsOn".
C:\Temp\serviceBus.bicep(115,3) : Error BCP037: The property "location" is not allowed on objects of type "Microsoft.ServiceBus/namespaces/networkRuleSets". Permissible properties include "dependsOn".
C:\Temp\serviceBus.bicep(126,3) : Error BCP037: The property "location" is not allowed on objects of type "Microsoft.ServiceBus/namespaces/queues". Permissible properties include "dependsOn".
C:\Temp\serviceBus.bicep(1009,3) : Error BCP037: The property "location" is not allowed on objects of type "Microsoft.ServiceBus/namespaces/topics". Permissible properties include "dependsOn".
C:\Temp\serviceBus.bicep(1117,3) : Error BCP037ac: The property "location" is not allowed on objects of type "Microsoft.ServiceBus/namespaces/topics/subscriptions". No other properties are allowed.
C:\Temp\serviceBus.bicep(4008,3) : Error BCP037: The property "location" is not allowed on objects of type "Microsoft.ServiceBus/namespaces/topics/subscriptions/rules". No other properties are allowed.

To Reproduce

1. Export an ARM template of a service bus resource in the Azure portal
2. Attempt to decompile that template to bicep.

Additional context After commenting out all location properties (except that on the root Microsoft.ServiceBus/namespaces resource), I was able to successfully decompile the template.

I think this is actually a combination of two bugs/limitations:

• Export filters out non-writable resource properties, but this only applies to values inside the "properties" body of a resource. "location" has not been declared as a valid writable property by the Resource Provider, so you'd expect it to be filtered out.
• The RP is returning "location" as part of a resource body, even though the location isn't strictly a property of the (child) resource.

The decompiler doesn't do any of its own filtering out based on type information, as this could be potentially destructive if we have type definition inaccuracies.

Also note that #3000 will result in these being warnings rather than errors with the next Bicep release.

@anthony-c-martin Are those bugs / limitations tracked elsewhere? If so, do you want to close this issue in favour of those.

This should now be a warning in 0.4.412. We'll leave this open to track the swagger fix.
