Question

Hi I m excited to start using FlyteRemote My first usecase is I d like to retrieve a launchplan and modify a default input before executing I have successfully done this for primitive inputs str int etc but FlyteRemote complained when I tried to pass in a ` dataclass json` class `Foo` It said i needed `types FooSchema` not `Foo` I assume there is some way to transform `Foo` into `FooSchema` using either dataclass json api or flyte api but I m not sure how to do it Could you direct me Exception and sample code in thread Thanks

I tried using ```proxy params schema ``` but received ```flytekit core type engine TypeTransformerFailedError Type of Val lt Level2proxyparametersSchema many=False gt is not an instance of lt class types Level2proxyparametersSchema gt ```

hey < Nicholas LoFaso> can you try providing the `type hints` argument to the `remote execute` call ```remote execute type hints= proxy params types Level2proxyparametersSchema ``` I ve come across this issue before if I recall correctly in my case it happened because the dataclass was defined programmatically and wasn t accessible in the module level scope Let me know what you get

Nicholas LoFaso · Answer

Incredible that was exactly the issue Thanks < Niels Bantilan> ```remote execute type hints= proxy params Level2ProxyParameters ```

Niels Bantilan · Answer

< Nicholas LoFaso> great just to confirm is `Level2ProxyParameters` being defined programmatically say within a function or is it defined in the top level scope of your module

Nicholas LoFaso · Answer

It s defined in a different package not within a function

Niels Bantilan · Answer

gotcha < Eduardo Apolinario eapolinario > < Yee> we should probably look into why the type transformer can handle these cases and raises ```flytekit core type engine TypeTransformerFailedError Type of Val lt Level2proxyparametersSchema many=False gt is not an instance of lt class types Level2proxyparametersSchema gt ``` if appropriate update the error message here to direct the user to use the `type hints` argument document this behavior better < Smriti Satyan> < Samhita Alla>

This workaround fixed things for us too If other people find this can add this to an issue if one exists will look in a minute be sure to pass default project and default domain when creating your remote object We passed them during fetch workflow and got an error during execute about missing project domain edit don t see an issue from may be tangentially related to but not trivially the same as this is about dataclasses
