Account name on different extractors

[zero0n3]

hi.
I currently use pixiv, deviantart, twitter and bluesky as extractors.

Initially I had configured the folder path as:
"directory": ["{category}", "{user[id]} {user[account]}", "{date:%Y}", "{date:%m}"],

As long as I used it only with pixiv, the folders came out fine. However, when I added the others, they started to appear, as the download folder "None None"

So I tried to use the field
{user[name]}

instead of [id] and [account]

but for twitter, bluesky, deviantart it continues to give me None.

I took a look at the configuration page and I expected to find a list of settings dedicated to the individual extractors. But I didn't find it.
So I ask you if this type of list exists or if I have a way to understand which field to declare for the individual extractors to create folders with the account name.
Thank you

The metadata names are somewhat different for each site.

You can get a list of available metadata names with -K:
