Anyone know how to remove a resource from pulumi that doesn’t exist in pulumi? So I’m getting this error saying a dataSource exists already, but when I do a
pulumi stack export > stack.json
, that data source does NOT exist in the file, also in pulumi web console it does NOT exist either.

Oh - I think
BadRequestException: Data source with name someLambdaDataSource already exists
is an error coming from AWS, not Pulumi. Are you saying you want your Pulumi program to delete a resource from AWS that was defined outside of Pulumi? That is not possible today.

If it was defined within a Pulumi stack and still exists, it should be in the state file and should have a URN. If it doesn’t, something must have gone wrong somewhere. But once it’s gone from your state file, Pulumi will not know how to manage it.

that’s my point, its not in the stack export. i can’t find it anywhere!
i guess ill check appsync data sources and manually remove if its there. thx for the help.
@white-balloon-205 manually removing the DataSource from AppSync fixed it.
