setProperties error

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)

4. Start to click on Run button
   
   

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

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