Using 'copy' in nested template variables triggered an template validation error
See original GitHub issueCurrently using azurerm-vscode-tools-0.10.1-alpha.20200520.vsix
Following template validation error is triggered: Template validation failed: Internal error: Validation threw an exception: The template function ‘copyIndex’ is not expected at this location. The function can only be used in a resource with copy specified. Please see https://aka.ms/arm-copy for usage details.
ARM template below can be successfully deployed without error:

@mvaferreira There is no validation cache, at the moment I think any copyIndex inside a nested template causes problems. @jorgecotillo is working on that.
@jorgecotillo It’s also odd that there’s no error location.
Thanks @StephenWeatherford I was able to repro the issue and was able to fix it, it was related to the expansion of copy function. The fix will be in v1.0.20
