Error: sed: -e expression #1, char 86: unknown option to `s'

Quote are just to prevent issues with the script that XWiki Helm is generating to add these values in files. 

Before, was working because the base file was "empty" and property key didn't exist before; then the command to append key=values was used. But now some keys exist; the sed command is generated to replace the value. 

Sadly, it's mess when we try to map values and pass values from multiple technologies (Yaml, Scripts Bash/SH, Java properties). 
Maybe someday we will discover a way to better handle this. 

I will close the issue; don't hesitate to reopen if necessary.
