BaseCase and input[type="file"]

[Saorhe]

I am trying to set up several automations and I am encountering two problems on two different web pages regarding the input to upload a doc.

My code is as follows:

` selector = 'input[type="file"]'

    if self.is_element_present(selector):
        print('-----------PRESENT-----------')
        
    if self.is_element_visible(selector):
        print('-----------VISIBLE-----------')

    if self.is_element_enabled(selector):
        print('-----------ENABLED-----------')  

    if self.show_element(selector):
        print('-----------SHOW-----------')  

    if self.is_element_clickable(selector):
        print('-----------CLICKCLICK-----------')  

    if self.is_element_in_an_iframe(selector):
        print('-----------IFRAME-----------')
        
    self.send_keys(selector,data['documents']['passport'])`

In this case only the PRESENT and ENABLED are printed and I always receive the error:

Element {input[type="file"]} was not visible after 7 seconds!

Not only when I do the send_keys but also when I do self.assert_element.

The input is not inside any frame or shadow-root. I have tried accessing the input by its ID, Xpath, class etc etc. The strange thing is that I have no problem uploading the document with php webdriver selenium, ui vision or the selenium python.

I have tried the demos or uploading files to the following websites and they go perfectly:
https://tus.io/demo
https://cgi-lib.berkeley.edu/ex/fup.html
https://seleniumbase.io/w3schools/file_upload

Has anyone found themselves in the same situation?
