Hidden FalsePositive Matching not working

[SolonRubens]

I got ltex-ls with Mason and lsp-zero installed.

In my lsp.lua I have the following line:

require("lspconfig").ltex.setup({ settings = { ltex = { language = "de-DE", hiddenFalsePositives = { "de-DE": [ "{\"rule\": \"UPPERCASE_SENTENCE_START\", \"sentence\": \"\\\\KBZ\"}" ] } } } })

But when I try to run :so I always get an error :
Error loading lua [string ":source (no file)"]:17: '}' expected (to close '{' at line 16) near ':'

I don't know where this comes from and what I could do about this

I just realized that this is the false repository I'm sorry for bothering
