What went wrong

I just configured yamlfix usage with ale in order to fix common errors in yaml files.
I went throught this process : https://lyz-code.github.io/yamlfix/#configure-environment-prefix to create some variables in my bashrc file:

# YAMLFIX config
export YAMLFIX_LINE_LENGTH="300"
export YAMLFIX_NONE_REPRESENTATION="null"
export YAMLFIX_SECTION_WHITELINES="1"
export YAMLFIX_COMMENTS_WHITELINES="1"
export YAMLFIX_EXPLICIT_START="false"
export YAMLFIX_quote_representation="'"

and configured this line in my vimrc file :

let g:ale_yaml_yamlfix_options = '--env-prefix "YAMLFIX_"'

These variables are not used at all and yamlfix continue to use default usage (adding "---" for example).
Did I miss something ?

YAMLFIX is already the default prefix, if you want to use that, you can simply skip the --env-prefix Parameter.
If you want to use something different, don't include the '_' in --env-prefix. (--env-prefix "YAMLFIX")
