unsupported type: %s

Error message

unsupported type: %s

What it means

Default-case guard in parseAsType: the reflect type of the config field being set does not match any of the known types (string, int, bool, []*config.UserSurvey, etc.) that the value parser knows how to construct. The field type is unsupported by `skaffold config set`.

Solutions

1. Edit the skaffold config file (~/.skaffold/config) directly for fields with unsupported types
2. Check whether a newer skaffold release supports the field type
3. Report the field name and type as an enhancement/bug to skaffold maintainers
