Close Browser

Close Browser

Type: browser-close  ·  Package: Browser v1.0.9

Closes the browser and frees its resources. It is the activity you finish a web automation with when you used Open Browser without body (Option B of the session model), or with keepOpen = true.

How it works

It receives any page session of that browser and closes the whole browser, with all its tabs (including the ones the website opened itself):

• It ends the browser process that Open Browser started.
• It deletes the temporary profile Chrome or Edge was opened with. With userDataDir, the person’s profile is not touched.
• If the browser was already closed (the person closed it, or it closed on its own), it doesn’t fail: it leaves a warning in the log and continues.

After this, no session of that browser can be used again.

Required parameters

Parameter	Type	Default	Description
session	ZoanPageSession	—	Any page session of the browser to close (from Open Browser, Attach Browser, New Page, Switch Page or Click with expectNewTab).

Optional parameters

None.

Output

This activity does not return a value.

Example

Open Browser   browser = chrome   → output: page
Page Navigate  page = page   url = "https://example.com"
... work ...
Close Browser  session = page

Do I need Close Browser?

Only in Option B (without body). If you use Open Browser with body, the browser closes on its own when the body finishes (unless you turn on keepOpen). To make sure it closes even if something fails midway, combine it with a Try / Catch and put Close Browser in the finally.

Common errors

Message	Cause and fix
'session' must be a valid ZoanPageSession or ZoanBrowserSession with a browser reference.	The variable is empty or doesn’t hold a browser session. Pass the output of Open Browser (or of another activity that returns a ZoanPageSession).
