error: azure-native:dbforpostgresql:Server resource 'postgresServer' has a problem: 'version' should be of type 'string' but got a number

[pyousefi]

What happened?

Deploying a postgresql server where the version number is in a config variable as a string (in quotes) is being returned as a number.

Example

Pulumi.dev.yaml:

config:
  storageSizeGB: 512
  version: '14' | "14" 

Pulumi.yaml:
version: ${version}

Thanks for opening the issue and sorry for the trouble!

I was able to reproduce this with the following program and setting the config via pulumi config set version 14:

name: azurenativenum
runtime: yaml
resources:
  resourceGroup:
    type: azure-native:resources:ResourceGroup
  server:
    type: azure-native:dbforpostgresql:Server
    properties:
      resourceGroupName: ${resourceGroup.name}
      version: ${version}

In the meantime, you can workaround by passing the value through fn::toJSON which will cast the number to a string (e.g. fn::toJSON: ${version}):

name: azurenativenum
runtime: yaml
resources:
  resourceGroup:
    type: azure-native:resources:ResourceGroup
  server:
    type: azure-native:dbforpostgresql:Server
    properties:
      resourceGroupName: ${resourceGroup.name}
      version:
        fn::toJSON: ${version}
