Generating images using Image prompt enhancer and DALL-E(-3) via Czech prompts doesn't work

[ceskyDJ]

What happened?

Hi, thanks for a great app! I noticed a pretty weird bug, when I try some prompts in Czech language. When I use Image prompt enhancer and DALL-E plugins, it just doesn't work. The error message is a little cryptic for me, so I don't know what cause it could have. Could you look at it, please?

Steps to Reproduce

1. Create new chat with gpt-4-turbo-preview
2. Add and activate plugin DALL-E or DALL-E-3 with Image promp enhancer at the same time
3. Give it some prompt in Czech for generating image, e.g. "Vygeneruješ mi prosím obrázek typický pro Českou republiku?"
4. It ends with an error "Something went wrong. Here's the specific error message we encountered: Encountered an error while attempting to respond: output values have 2 keys, you must specify an output key or pass only 1 key as output"

What browsers are you seeing the problem on?

Chrome

Maybe it's good to explicitly say that the same configuration works with English prompts.
