[Bug]: RuntimeError: There is no current event loop in thread 'AnyIO worker thread'.

[Gushousekai195]

What happened?

I clicked Dream and it didn't work.

The console returned this error:

API error: POST: https://info-kirk-singer-responsible.trycloudflare.com/sdapi/v1/img2img {'error': 'RuntimeError', 'detail': '', 'body': '', 'errors': "There is no current event loop in thread 'AnyIO worker thread'."}

seems to be equivalent to https://github.com/zero01101/openOutpaint-webUI-extension/issues/46 but i'll leave this issue here in case people check this repo instead

have you seen this issue? could you try going to http://127.0.0.1:7860/docs#/default/text2imgapi_sdapi_v1_txt2img_post, click try it out and populate the request body input with

{
    "batch_size": 1,
    "cfg_scale": 7,
    "enable_hr": false,
    "height": 512,
    "n_iter": 1,
    "negative_prompt": "test",
    "prompt": "test",
    "restore_faces": false,
    "sampler_index": "DDIM",
    "seed": "1",
    "steps": 1,
    "width": 512
}

and execute it? it should return a base64 string if webUI's API is returning images successfully

yeah, this is almost certainly going to be in webUI given the consistency of the issue and how it seems to be presenting itself, plus https://github.com/AUTOMATIC1111/stable-diffusion-webui/issues/9046 and https://github.com/AUTOMATIC1111/stable-diffusion-webui/pull/9319 are kind of a giveaway... closing for now, but if it continues to happen after 9319 (or similar) is merged, then feel free to reopen
