Hey @Skraye
We need to handle this check for OutputValues tasks on the frontend and also modify the error message?
Because the sub type can only be a string for output values right?

Hello @Malaydewangan09
Effectively, for some reason, we decided to go with a Map<String, String>, but now I think it should have been a Map<String, Object> to allow nested maps & arrays.
