I want to use a special and uncommon option package for bibtex: BIBLATEX-SWISS-LEGAL-BASE CTAN. I resume my document as following:

    \usepackage[style=biblatex-swiss-legal-bibliography, backend=biber]{biblatex}   %The code work with default config
        author = {Lours, Donald},
        year = {1977},
        title = {L'origine du monde},

Je doute de mes capacités à résoudre ce problème \cite{LoursKnuth}.

Since the transformation of bibtex 3.3 the package is no more usable and display this kind of error:

! Illegal parameter number in definition of \blx@defformat@d.
<to be read again>
l.355 \usebibmacro{name:last}{\ifblank{#5}{}{\textsc{#5}\addspace}\textsc...
You meant to type ## instead of #, right? Or maybe a } was forgotten somewhere earlier, and things are all screwed up? I'm going to assume that you meant ##.

I imagine that the package has to be maintained but meanwhile is it possible to use a simple "fix tip" for all this. As far as I didn't write myself the package, make correction in the macros is not possible for me (like in Biblatex 3.3 name formatting).

I remplaced the biblatex-swiss-legal-base provided by @moewe as suggested in answer about the same problem. it didn't fix completly the problem, the following error appear:

l.215 \DeclareSortingTemplate
{ntyintro}{% Code en test non mentionné dans l...
The control sequence at the end of the top line of your error message was never \def'ed. If you have misspelled it (e.g., `\hobx'), type `I' and the correct spelling (e.g., `I\hbox'). Otherwise just continue, and I'll forget about whatever was undefined.

it happens in the corrected .bbs avaiable here. and then a worst one: ! LaTeX Error: Missing \begin{document}.

    There is an unofficial update for biblatex-swiss-legal-bibliography written by moewe, the developer of BibLaTeX. You can download it from gist.github.com/moewew/c15dcbe6a7a23e007a9ed65b7d7aa567, see also tex.stackexchange.com/questions/426142/…. I checked and it works with your MWE. To use it you should download the file, put it in the same directory as your .tex file and remove the -new part from the filename. – Marijn Sep 3 '19 at 20:16
  • Thank you! I completed my question, because it doesn't work yet... – Dimitri Paratte Sep 4 '19 at 14:49
  • Which version of biblatex do you use? You can find the version number in the log file (search for Package: biblatex). The \DeclareSortingTemplate macro was introduced in version 3.8, November 2017. – Marijn Sep 4 '19 at 15:17
  • Indeed, i've got an older version of biblatex. I reinstall a new LTS and brand new texlive. It works queit well whith this patch! That's truely great. Wouldn't be possible to write it in the CTAN biblatex-swiss-legal page that this unofficial update exists? I wrote to both last maintainer, but waiting for their answer it would be great to make this update circulating... Thanks a lot! – Dimitri Paratte Sep 6 '19 at 10:47
  • I'm the author of the changed version of the .bbx file Marijn linked in their comment above. I have no intention of uploading the changed version to CTAN nor do I intend to support or maintain the ad-hoc changes I made for future versions of biblatex of my own accord. I will, however, consider my changes to the original file to be made under the LPPL so that it would be possible for anyone who is interested to use and/or distribute the file in the same way as the biblatex-swiss-legal package. ... – moewe Sep 6 '19 at 15:37
