ValueError: AutoPipeline can't find a pipeline linked to SanaPipeline for None

[RageshAntonyHM]

Since SanaPipline has been added to Diffusers as a custom pipeline it is possible to use SanaPipeline from diffusers.

But when trying to use AutoPipelineForText2Image which automatically selects the needed custom pipeline for a model ID, it fails to work by throwing an error:

Traceback (most recent call last):

ValueError: AutoPipeline can't find a pipeline linked to SanaPipeline for None

Codeblock:

    b_pipe = AutoPipelineForText2Image.from_pretrained(
        config["Efficient-Large-Model/Sana_1600M_1024px_BF16_diffusers"],
        torch_dtype=torch.bfloat16
    ).to("cuda")

What is the reason for this error ? Please help me.
