I am getting the below error with awsx using golang:

error: no resource plugin 'pulumi-resource-awsx' found in the workspace at version v1.0.0-testplsignore.0 or on your $PATH, install the plugin using `pulumi plugin install resource awsx v1.0.0-testplsignore.0`

I try installing the said plugin and the URL seems to be busted

➜ vpcx pulumi plugin install resource awsx v1.0.0-testplsignore.0 
[resource plugin awsx-1.0.0-testplsignore.0] installing
error: [resource plugin awsx-1.0.0-testplsignore.0] downloading from : 403 HTTP error fetching plugin from <https://get.pulumi.com/releases/plugins/pulumi-resource-awsx-v1.0.0-testplsignore.0-darwin-amd64.tar.gz>

could you file a github issue for this?

Sure.
