ESLint vue/valid-v-slot

Question

Add the eslintrc.js file to my Vue project to configure the ESLint rules, and I have a problem with vue/valid-v-slot, which initially showed errors where I used v-slot. Then, I set it up as follows (recommended by the documentation and in other posts):

"vue / valid-v-slot": ['error', {"allowModifiers": false}],

but it doesn't work. I get the following error message:

Syntax Error: Error: .eslintrc.js:
         Configuration for rule "vue / valid-v-slot" is invalid:
         Value [{"allowModifiers": false}] should NOT have more than 0 items.
     at Array.forEach (<anonymous>)

Here are the installed dependencies:

How can I solve that?
