setProperties error

[PavelLaptev]

Sometimes when I generate and set new props randomly with API, I’m getting this error.

which is strange because the instance props I want to replace, and new props, are the same

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?

[PavelLaptev]

@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.

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!
