Create inspiration images script not working

[schoenid]

Installed like proposed:

Content of the file "artist.txt":

Loading script:

Result:

TypeError: Script.run() missing 2 required positional arguments: 'prompt_placeholder' and 'files'
Time taken: 0.0 sec.

readme.md with:

• Run the "Create inspiration images" script inside the "txt2img" page to create images.

Does not tell how ... using the "Generate" button?

Look here for more install details

does not really tell me more about the installation.
I do know now, something is missing. But what exactly and where?
'prompt_placeholder' and 'files' are defined in the script placeholders. So why this error?
