kling-image-o1 does not support series generation.

Error message

kling-image-o1 does not support series generation.

What it means

Raised by OmniProImageNode.execute when series generation is enabled (series_amount != 'disabled') and model_name is 'kling-image-o1'. The o1 image model has no series (multi-image story set) output, so result_type='series' requests are rejected client-side before the API call.

Solutions

1. Set series_amount to 'disabled' when using kling-image-o1
2. Keep series generation on the non-o1 kling-image models
3. If multiple o1 variations are needed, loop the node with different seeds/prompts

Example fix

// before
model_name = "kling-image-o1"
series_amount = "4"

// after
model_name = "kling-image-o1"
series_amount = "disabled"

def o1_series_ok(model_name: str, series_amount: str) -> bool:
    return model_name != "kling-image-o1" or series_amount == "disabled"

When it happens

Trigger: model_name='kling-image-o1' with the series_amount combo set to anything other than 'disabled' (e.g. '4').

Common situations: A workflow built for kling-image-2 series generation is switched to o1 to try the newer model, leaving series_amount populated.
