Please add steps to reproduce the bug. Also tell if all required components (variants) exist in the component set? Can you add a link to the test file and sample code?

@tank666 sure

1. 
   

   Open this file https://www.figma.com/file/2iQtWRfyqEOZo0udal3lqD/Test-file?node-id=0%3A1&t=HZ7z7PAmo0oLygXl-1

   
   


2. 
   

   Select the Component Awesome instance
   
   

   
   
   


3. 
   

   Run Scripter plugin

   
   


4. 
   

   Paste this code

   
   

const instanceVariant = figma.currentPage.selection[0] as InstanceNode



const sortProperties = (arr: string[]) => {

  const props = {};

  arr.forEach((str) => {

    str.split(",").forEach((pair) => {

      const [prop, value] = pair.trim().split("=");

      if (!props[prop]) {

        props[prop] = [];

      }

      if (!props[prop].includes(value)) {

        props[prop].push(value);

      }

    });

  });

  Object.keys(props).forEach((key) => {

    props[key].sort();

  });

  return props;

};



function getRandomValues(obj) {

  const result = {};

  for (const prop in obj) {

    const values = obj[prop];

    const randomIndex = Math.floor(Math.random() * values.length);

    result[prop] = values[randomIndex];

  }

  return result;

}



const allVariantsNamesArr = instanceVariant.mainComponent.parent.children.map(

	(child) => child.name

);



const sortedVariants = sortProperties(allVariantsNamesArr)



const randomProps = getRandomValues(sortedVariants)



instanceVariant.setProperties(randomProps)



// console.log(randomProps)

some “runs” will be successful, but some not.

Thanks for the detailed answer.

The error occurs because your component set is missing variants:

• Size=small, Radius=on, Rotate=on;


• Size=medium, Radius=on, Rotate=on;


• Size=big, Radius=on, Rotate=on.

You’re right, I didn’t think about that 🫠 Thanks for your help!
