5 months ago To resolve the error thrown by the Stable Diffusion webui tool after modifying the DRAW_TEXT_OPTIONS dictionary, ensure that the modifications you made are correctly reflected in the code where draw_options is used. Specifically, make sure that any new keys you added to DRAW_TEXT_OPTIONS are properly handled in the text2img and img2img methods.
Here is an example of how you can ensure the draw_options dictionary is correctly populated:
def text2img(self, base_url: str, lora: str, prompt: str, negative_prompt: str, width: int, height: int, steps: int, model: str) \
-> Union[ToolInvokeMessage, list[ToolInvokeMessage]]:
"""
generate image
"""
# copy draw options
draw_options = deepcopy(DRAW_TEXT_OPTIONS)
if lora:
draw_options['prompt'] = f'{lora},{prompt}'
else:
draw_options['prompt'] = prompt
draw_options['width'] = width
draw_options['height'] = height
draw_options['steps'] = steps
draw_options['negative_prompt'] = negative_prompt
draw_options['override_settings']['sd_model_checkpoint'] = model
# Ensure any new keys are handled here
# For example, if you added a new key 'new_option' in DRAW_TEXT_OPTIONS
# draw_options['new_option'] = some_value
try:
url = str(URL(base_url) / 'sdapi' / 'v1' / 'txt2img')
response = post(url, data=json.dumps(draw_options), timeout=120)
if response.status_code != 200:
return self.create_text_message('Failed to generate image')
image = response.json()['images'][0]
return self.create_blob_message(blob=b64decode(image),
meta={ 'mime_type': 'image/png' },
save_as=self.VARIABLE_KEY.IMAGE.value)
except Exception as e:
return self.create_text_message('Failed to generate image')Ensure that any new keys you added to DRAW_TEXT_OPTIONS are correctly set in the draw_options dictionary before making the API call. This will help in resolving the error.
Additionally, you can check the specific error logs or stack traces generated by the Stable Diffusion webui tool to gain more insight into the root cause of the error. If you continue to experience issues, please provide the specific error message or stack trace you are encountering, as this will help in further diagnosing the problem.

Steps to reproduce
I used the stable diffusion webui tool in workflow and I was not getting any output from the tool Solved this Issue by changing this in api/core/tools/provider/builtin/stablediffusion/tools/stable_difussion.py: DRAW_TEXT_OPTIONS = { "prompt": "", "negative_prompt": "", "seed": -1, "subseed": -1, "subseed_strength": 0, "seed_resize_from_h": -1, 'sampler_index': 'DPM++ SDE Karras', "seed_resize_from_w": -1, "batch_size": 1, "n_iter": 1, "steps": 10, "cfg_scale": 7, "width": 1024, "height": 1024, "restore_faces": False, "do_not_save_samples": False, "do_not_save_grid": False, "eta": 0, "denoising_strength": 0, "s_min_uncond": 0, "s_churn": 0, "s_tmax": 0, "s_tmin": 0, "s_noise": 0, "override_settings": {}, "override_settings_restore_afterwards": True, "refiner_switch_at": 0, "disable_extra_networks": False, "comments": {}, "enable_hr": False, "firstphase_width": 0, "firstphase_height": 0, "hr_scale": 2, "hr_second_pass_steps": 0, "hr_resize_x": 0, "hr_resize_y": 0, "hr_prompt": "", "hr_negative_prompt": "", "script_args": [], "send_images": True, "save_images": False, "alwayson_scripts": {} } to this: DRAW_TEXT_OPTIONS = { "prompt": "", "negative_prompt": "", "seed": -1, "subseed": -1, "subseed_strength": 0, "seed_resize_from_h": -1, "seed_resize_from_w": -1, "batch_size": 1, "n_iter": 1, "steps": 10, "cfg_scale": 7, "width": 1024, "height": 1024, "restore_faces": False, "do_not_save_samples": False, "do_not_save_grid": False, "eta": 0, "denoising_strength": 0, "s_min_uncond": 0, "s_churn": 0, "s_tmax": 0, "s_tmin": 0, "s_noise": 0, "override_settings": {}, "override_settings_restore_afterwards": True, "refiner_switch_at": 0, "disable_extra_networks": False, "comments": {}, "enable_hr": False, "firstphase_width": 0, "firstphase_height": 0, "hr_scale": 2, "hr_second_pass_steps": 0, "hr_resize_x": 0, "hr_resize_y": 0, "hr_prompt": "", "hr_negative_prompt": "", "script_args": [], "send_images": True, "save_images": False, "alwayson_scripts": {} }
✔️ Expected Behavior
Get an Image
❌ Actual Behavior
Through an error.
