tesseract: user_words_suffix not working

We are trying to provide a user words file via available control params. Unfortunately I am getting below error -

Environment

Tesseract Version: tesseract 4.00.00alpha leptonica-1.74.4 libgif 5.1.4 : libjpeg 8d (libjpeg-turbo 1.5.1) : libpng 1.6.34 : libtiff 4.0.8 : zlib 1.2.11 : libwebp 0.6.0 : libopenjp2 2.2.0 Found AVX Found SSE
Platform: Linux 9cadf37d2e9c 4.9.49-moby #1 SMP Wed Sep 27 23:17:17 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

Current Behavior:

Using below params to supply user words file -

tesseract --user_words_file /usr/share/tesseract-ocr/4.00/tessdata/eng.user-words    -psm=1 -l=eng source.ppm res11 txt

I am getting error as -

read_params_file: parameter not found: P6

Is this supported in above tesseract version? I can see the support is mentioned in the help

user_words_file		A filename of user-provided words.
user_words_suffix            A suffix of user-provided words located in tessdata.
user_patterns_file            A filename of user-provided patterns.
user_patterns_suffix        A suffix of user-provided patterns located in tessdata.

Please note I have tried all possible options to supply the file - user_words | user_words_file | user_words_suffix | user_patterns_file | user_patterns_suffix

Please suggest the right way to achieve the same.

Thanks,

Ok, I added the lines to Dict::LoadLSTM and it works, with the the following:

# tesseract test.png stdout --tessdata-dir ./tessdata --oem 0 -c page_separator=''
Dnline

# tesseract test.png stdout --tessdata-dir ./tessdata --oem 0 -c page_separator='' bazaar
