There is no setting to disable SSL verification in watcher http input

Hi Team,
I am using elasticsearch watcher http input to read list of values. but when I configured its showing

    "type": "s_s_l_handshake_exception",
        "reason": "PKIX path building failed: unable to find valid certification path to requested target",

I search on documentation page, I didn't see any option to disable SSL cert verification.

Is there any other way to avoid this error or setting in watcher input?
