I got a syntax error in my async function

I'm trying to make a function that can loop through Instagram photos and like them one by one but I couldn't figure out the syntax error I got.

likeTagsProcess = async (tags = []) => {
    for (let tag of tags) {

        // Go to the hashtag page
        await instagram.page.goto(TAG_URL(tag), {
            waitUntil: 'networkidle2'
        });

        await instagram.page.waitFor(1000);

        let posts = await instagram.page.$$('article > div:nth-child(3) img[decoding="auto"]');

        for (let i = 0; i < 3; i++) {

            let post = posts[i];

            // Click on the post
            await post.click();

            // Wait for the modal to appear
            await instagram.page.waitFor('span[id="react-root"][arria-hidden="true"]');
            await instagram.page.waitFor(1000);


            // Liking Posts
            let isLikable = await instagram.page.$('span[aria-label="Like"]');

            if (isLikable) {

            // Clicking Like
            await instagram.page.click('span[aria-label="Like"]');

            }

            await instagram.page.waitFor(2500);

            // Close the modal 


            await instagram.page.click("body > div._2dDPU.CkGkG > div.Igw0E.IwRSH.eGOV_._4EzTm.BI4qX.qJPeX.fm1AK.TxciK.yiMZG > button > svg");
            await instagram.page.waitFor(1000);
        }

        await instagram.page.waitFor(10000);

    }
}

typescript throws this error:

               ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
