az cli incorrect parsing of query "--query "[0].keys(@)"

This is autogenerated. Please review and update as needed.

Describe the bug

I get an error message (see below) when I issue the following command. The command should output the structure of the json data.

Command Name az vm list -d --query "[0].keys(@)"

Errors:

az vm list: error: argument --query: invalid jmespath_type value: '[0].keys(@'
usage: az vm list [-h] [--verbose] [--debug] [--only-show-errors]
                  [--output {json,jsonc,yaml,yamlc,table,tsv,none}]
                  [--query JMESPATH] [--subscription _SUBSCRIPTION]
                  [--resource-group RESOURCE_GROUP_NAME] [--show-details]

C:\>echo Failed to load python executable.
Failed to load python executable.

C:\>exit /b 1

As you may notice in the error message the closing parenthesis of the query is missing. So I reissued the slightly modified command with an extra space after the closing parenthesis:

az vm list -d --query "[0].keys(@) "

Et Voilà:

[
  "location",
  "tags",
 ... skipped for prevety
 "privateIps",
  "macAddresses",
  "resourceGroup"
]

To Reproduce:

See above.

Expected Behavior

The command should output the keys of the json describing the vm.

Additional Context

[ralfkret]

At least now I have an idea why the variant with the extra space az vm list --query "[0].keys(@) " worked.

I assumed any character would do, but the real difference seems to be that the whitespace prevents prevents PowerShell from stripping the quotes as mentioned in Quoting issues with PowerShell.

This is confirmed by the fact that the following variants of the command work as expected (in PowerShell):

az vm list --query " [0].keys(@)"

az vm list --query "[0].keys( @ )"

Well - live and learn.

I can’t run this command and got error #15064. @qwordy

It is a service issue after my investigation.
