File Chooser Not Opening on Upload Button Click

[sarathselvi]

When automating a file upload flow, clicking the upload button does not open the file chooser window. This issue occurs in both Chromium and Firefox when run through automation. However, the same flow works as expected in a regular Chrome browser on macOS. This affects both static elements and dynamically triggered file uploads.

Environment
• OS: macOS
• Headless/Headed: Headded

Expected
File chooser should open when upload button is clicked.

Hi, could you share what version of @playwright/mcp you're running with, and a prompt we can use to reproduce it? What website is this happening on?

[sarathselvi]

Version of @playwright/mcp is v0.0.9;

Prompt I used - click 'Choose File', and then select {file-name}.pdf file from the file chooser

file_upload.html.zip

I created a sample html to accept file upload.

Two problems here:

• 'then select {file-name}.pdf file from the file chooser' part. You need a computer use agent rather than a browser use agent to access the native file chooser dialog. But if you are using VS Code or Cursor they should be able to pick a file from workspace.
• The aria snapshot is flawed:

<input type="file" id="staticFileInput">

is reported as

- textbox

rather than a button. I'll need to fix that.
