Upload is not working with WebElementFacade

[jurec72]

What happened?

Hi,
I use latest Serenity version and have issue with upload file when use sendKeys or upload().to() on Selenium , Java.
Error:
org.openqa.selenium.ElementNotInteractableException: Timed out after 3 seconds. Element not available.

Code example:
` @findby(xpath = "//input[contains(@Class,'TaskAttachments_task-attachments__upload-field')]")
public WebElementFacade attachmentsInput;

public void test() {
File file = new File(IFilePaths.FILES_TDOC_FOLDER, "default.tdoc");
upload(file.getPath()).to(tasksPanelPage.attachmentsInput);
}
or
public void test() {
File file = new File(IFilePaths.FILES_TDOC_FOLDER, "default.tdoc");
tasksPanelPage.attachmentsInput.sendKeys(file.getPath());
}
`

But when I use just By element then it is working:

`
public void test() {
File file = new File(IFilePaths.FILES_TDOC_FOLDER, "default.tdoc");
upload(file.getPath()).to(find(tasksPanelPage.attachmentsInput));
}

or

By attachmentsInput = By.xpath("//input[contains(@Class,'TaskAttachments_task-attachments__upload-field')]");

public void test() {
File file = new File(IFilePaths.FILES_TDOC_FOLDER, "default.tdoc");
find(tasksPanelPage.attachmentsInput).sendKeys(file.getPath());
}
`

What did you expect to happen?

Should upload file with WebElementFacade.

Serenity BDD version

How to reproduce the bug.

Steps to reproduce:

• upload any file to any website by using WebElementFacade!

How can we make it happen?

Work on this myself and propose a PR (with Serenity BDD team guidance)

Have a look at the code, but I'm not sure this is Serenity-related. find() returns a WebElementFacade, so the code is very similar - that said, I never use @findby because I find it unreliable in general.
