Help with Running Taiko in Firefox Nightly

[DevaIrakkamRubavathy]

Hi! I'm trying to run npx taiko on MacOS (intel, if it matters) with a Firefox Nightly browser using the following command :

TAIKO_BROWSER_PATH="/Applications/Firefox\ Nightly.app/Contents/MacOS/firefox" taiko                

Version: 1.2.5 (/Applications/Firefox\ Nightly.app/Contents/MacOS/firefox)
Type .api for help and .exit to quit

Warning: Please check if TAIKO_BROWSER_PATH (/Applications/Firefox\ Nightly.app/Contents/MacOS/firefox)
points to a valid browser executable file.

> openBrowser()
 ✘ Error: Tried to use TAIKO_BROWSER_PATH env variable to launch browser but did not find any executable at: /Applications/Firefox\\ Nightly.app/Contents/MacOS/firefox, run `.trace` for more info.'

I am getting this error, but the path given is correct.

If anybody know how to fix this, please help me out.
TIA!

It is working after removing the double quotes in the TAIKO_BROWSER_PATH. But it is throwing some error after running openBrowser() command.

TAIKO_BROWSER_PATH=/Applications/Firefox\ Nightly.app/Contents/MacOS/firefox taiko

Version: 1.2.5 (/Applications/Firefox Nightly.app/Contents/MacOS/firefox)
Type .api for help and .exit to quit

> openBrowser()
Target.getTargetInfo (RemoteAgentError@chrome://remote/content/cdp/Error.jsm:29:5

)

If anybody know how to fix this, please help me out.
TIA!
