API error: 422 response from StableDiffusion API for txt2img/img2img

Photoshop plugin version: 1.4.1
A1111 extension: [6f6d4907](https://github.com/AbdullahAlfaraj/Auto-Photoshop-StableDiffusion-Plugin/commit/6f6d4907adf0b6a6e562d084238f02ed6b7503c1)

I'm getting 422 http responses from A1111 SD API when I generate txt2img (or any mode) from the photoshop plugin.

For example with api logging turned on, I see:

```
2024-05-15T23:07:20.995698136Z API 2024-05-15 23:07:20.785580 422 http/1.1 POST /sdapi/v1/txt2img {ip address removed} 0.0036
```

I can curl and post to the API manually, e.g. with something like:

```
curl -X 'POST' 'https://$WAN_URL/sdapi/v1/txt2img' -H 'accept: application/json' -H 'Content-Type: application/json' -d '{
"prompt": "a bowl of cherries",
"negative_prompt": "",
"styles": [
"string"
],
"seed": -1,
"subseed": -1,
"subseed_strength": 0,
"seed_resize_from_h": -1,
"seed_resize_from_w": -1,
"sampler_name": "DPM++ 2M",
"scheduler": "karras",
"batch_size": 1,
"n_iter": 1,
"steps": 35,
"cfg_scale": 7,
"width": 1024,
"height": 1024
}'

```

That works from the same network as my SD plugin.

So I enabled A1111 api logging with `--api-log` and I'm getting `422` errors

You'll also note log lines for getting the LoRAs and VAEs and models and whatnot, those work and the model list is updated in the photoshop plugin.

Any ideas appreciated -- also, love this plugin! Thanks for the hard work on it. I have it working on another machine and it works fine, which is baffling

Additionally I noticed a `log errors to file` option in the photoshop plugin, but, unsure where that file would live.

Thanks!
