According to the modular pipeline docs, parameters can be remapped to new names using a dict (https://kedro.readthedocs.io/en/stable/kedro.pipeline.modular_pipeline.pipeline.html), but I'm not sure I'm getting it - the dict I'm passing to the

pipeline

wrapper is of the form

{'existing_param':'new_param'}

. However I'm getting an error similar to

kedro.pipeline.modular_pipeline.ModularPipelineError: Failed to map datasets and/or parameters: existing_param

. Digging up a bit I found the code that checks the existence of the parameters:

existing = {_strip_transcoding(ds) for ds in pipe.data_sets()}
    non_existent = (inputs | outputs | parameters) - existing
    if non_existent:
        raise ModularPipelineError(
            f"Failed to map datasets and/or parameters: "
            f"{', '.join(sorted(non_existent))}"
        )

What I don't understand is that

existing

only includes datasets, not params. What am I missing here 😅
