Additional context

I was wondering if this could come from specific caracters in the filter values ? That's why I copied paste the parameter window.

Can you try the latest wip.
It contains a revamped color splasher

The latest WIP did not solve it, it is due to the name of the filter containing

DEBUG [ColorSplasher] Exception value: name cannot include prohibited characters, such as "{, }, [, ], |, ;, less-than sign, greater-than sign, ?, `, ~". 

[jmcouffin]

fixed by #2514
unwanted character in filtername being ':'
I am glad I took the time to implement proper debugging 😄

[jmcouffin]

and @dsellam your explanaition was great to resolve it.

[dsellam]

if you follow the link to the PR #2514
You will find the latest wip in the thread
answer is: YES
