unable to write .json files _all_external and _external flags

[magicbot42]

Due diligence

• I checked for similar issues and couldn't find any.
• My WebUI and Unprompted are both up-to-date.
• I disabled my other extensions but the problem persists.

Describe the bug

I would like to write out external variables, and read them back in as a solution to an issue where with the same seed and prompt in img2txt and in img2img I am having issues with img2img not using the same variable for the same side as was used in txt2img. I think this other issue may be related to a previous post about unprompted becoming non-deterministic at some point. I wanted to work around it with the new _external and _all_external optiosn you added recently, but I can't get them to work. I get the traceback below:

I tried both:
[set animal _external="F:\SD\stable-diffusion-webui\extensions_unprompted\templates\x\data.json"]cat[/set]

and:
[set animal]cat[/set]
[sets _all_external="F:\SD\stable-diffusion-webui\extensions_unprompted\templates\x\data.json"]

For both of these, I'm getting this same traceback:

Prompt

I tried both:
[set animal _external="F:\SD\stable-diffusion-webui\extensions_unprompted\templates\x\data.json"]cat[/set]

and:
[set animal]cat[/set]
[sets _all_external="F:\SD\stable-diffusion-webui\extensions_unprompted\templates\x\data.json"]

Hi @magicbot42,

I can confirm that you're using the correct syntax - both of your examples write to the data.json file on my machine.

I'm wondering if it's tripping on the initial loading of an empty JSON file. Could you try making the file manually and adding {"anything": "here"}, save it, then running your example prompt again? Let me know if that changes anything, please.
