Error providing aws.allowedAccountIds in sst.config.ts

[cmanou]

In particular setting providers.aws.allowedAccountIds in Config.app of sst.config.ts which has typescript type $util.Input<$util.Input<string>[]> which is basically string[] gives

panic: json: cannot unmarshal array into Go struct field App.providers of type string

goroutine 1 [running]:
main.main()
    /home/runner/work/ion/ion/cmd/sst/main.go:659 +0xa88

Looks like it's to do with the struct for app providers only allowing string values in the following file.

ion/pkg/project/project.go

Line 19 in 955765a

Providers map[string]map[string]string `json:"providers"`
