AWS Chatbot SlackChannelConfiguration update fails

[Tirke]

👋

I've deployed some SlackChannelConfiguration.

new chatbot.SlackChannelConfiguration(`slack-bot-${env}`, {
    configurationName: `${env}-slack-bot-config`,
    iamRoleArn: iamRole.arn,
    slackChannelId,
    slackWorkspaceId,
    snsTopicArns: [pushTopic.arn],
    loggingLevel: 'ERROR',
  })

Later I made some change on the IAM policy that resulted in the role replacement and while trying to update the SlackChannelConfiguration, pulumi failed with that error operation error CloudControl: UpdateResource, https response error StatusCode: 400, RequestID: be889c61-f25e-40b4-9aea-acda68952071, api error ValidationException: Model validation failed (#/GuardrailPolicies/0: failed validation constraint for keyword [pattern]).

I then saw here: https://github.com/pulumi/pulumi-aws-native/blob/a06f8f064492741ce1f5f91c7d901836f62a24ed/sdk/nodejs/chatbot/slackChannelConfiguration.ts#L46-L48

That there is some magic around guardrailPolicies if you don't explicitly define them. I went ahead and added guardrailPolicies: ['arn:aws:iam::aws:policy/AdministratorAccess'] to my conf, and it fixed the issue.

From the user perspective this is not great because error message is complicated and the behaviour is weird. Is it possible to improve this?
