Formatting njk files by printer or other solution

[mr-scrpt]

Hello all. I want to set up a formatting pritter there so that my nunjucks files are formatted as html files. Trying several options, for example I have this setting
vim.cmd('au BufRead,BufNewFile *.njk set filetype=html')
or
vim.cmd('au BufRead,BufNewFile *.njk set filetype=htmldjango')
In the first case I get no formatting and get an error

In the second case, there is no error, but no formatting, although the same file but with the extension html is formatted without problems and has no error
I tried experimenting with the settings but it did not help me

  let g:ale_fixers = {
                    \ '*': ['remove_trailing_lines', 'trim_whitespace'],
                    \ 'html': ['prettier'],
                    \ 'javascript': ['eslint', 'prettier'],
                    \ 'css' : ['stylelint', 'prettier'],
                    \ 'scss' : ['stylelint', 'prettier'],
                    \ 'htmldjango' : [ 'prettier'],
                    \ 'njk' : [ 'prettier'],
                    \ }

Please tell me how I can get this to work.
