Source code

We are using the following code for a file upload:

final FileChooser fileChooser = page.waitForFileChooser( ( ) -> page.locator( "..." ).click( ) );
fileChooser.setFiles( new FilePayload( ... );

This works up to 1.39.0, but since 1.40.0 following error occurs:

com.microsoft.playwright.PlaywrightException: Error {
  message='Exactly one of payloads, localPaths and streams must be provided
  name='Error
  stack='Error: Exactly one of payloads, localPaths and streams must be provided

We are using the docker image "yukinying/chrome-headless-browser-stable:120.0.6099.224" within Testcontainers for our tests, so this should be compatible with 1.41.1.

I will try and provide a self contained example for this, but I would still ask you to check whether you can confirm this issue.

Thank you and best regards

I'll cherry pick it into 1.41.2
