There seems to be a race condition between "waitForFileChooser" and "click" when I try to automate uploading files according to the puppeteer's documentation of API.
Sometimes it works, sometimes it doesn't, so how can I solve this issue?
TimeoutError: waiting for file chooser failed: timeout 30000ms exceeded.
const [fileChooser] = await Promise.all([
page.waitForFileChooser(),
page.click('#upload-file-button'), // a button that triggers file selection
]);
await fileChooser.accept(['someFile.pdf']);
You can increase the timeout for waitForFileChooser (see https://pub.dev/documentation/puppeteer/latest/puppeteer/Page/waitForFileChooser.html):
// ...
page.waitForFileChooser({timeout: 50000}),
// ...
