Sampler error on text to image - SAMPLER_K_DPMPP_2M - No such sampler

[elvinagam]

Getting no such sampler error. What might be a reason? Using the same copy pasted code from your api documentation

def generate_stability(self, prompt, negative_prompt="", edit_parameter=-1, seed=4, steps=50, cfg_scale=8.0,
                           width=1024, height=1024, samples=4, sampler=generation.SAMPLER_K_DPMPP_2M):
        # sampler is sensitive
        try:
            stability_api = client.StabilityInference(
                key=self.key,
                verbose=True,
                engine="stable-diffusion-xl-1024-v1-0"
            )

            answers = stability_api.generate(
                prompt=[generation.Prompt(text=prompt, parameters=generation.PromptParameters(weight=1)),
                        generation.Prompt(text=negative_prompt, parameters=generation.PromptParameters(weight=edit_parameter))],
                seed=seed,
                steps=steps,
                cfg_scale=cfg_scale,
                width=width,
                height=height,
