用api调用多帧渲染的脚本的时候报错

[hexiaochun]

用webui界面去调用的时候是没有问题的
用api去调用的时候就报一个mask读取失败的错误，导致controlnet 没有效果

api的请求参数如下：
` ``
res = api.img2img(images=[input_img],inpainting_fill=1,mask_blur=4,mask_image=None,inpaint_full_res=0,inpaint_full_res_padding=32
,prompt=words,negative_prompt=data["negative_prompt"],seed=data["seed"],
cfg_scale=data["cfg_scale"],denoising_strength=data["denoising_strength"]
,restore_faces=True,width=w,height=h,steps=data["steps"],sampler_name=data["sampler_name"],batch_size=1,controlnet_units=[unit1,unit2]
,script_name="multi-frame rendering",script_args=[
'None',
input_path,
output_path,
'',
data["denoising_strength"],
"FirstGen",

                True,
                False,
                "Current",
                False,
                '1 2 3 \r\n 0',
                
                False,
                "",
                True,
                '',
                False,
                '',
                False,
                *['','']
            ])

对比了一下网页送入的参数是一致的，怀疑是p这个参数里面的值不一致，又做了对比发现也是一样的，
错误信息如下：

During handling of the above exception, another exception occurred:

请问这个该从哪个地方入手
