WARNING: calling IsSet with unsupported type "invalid" (<nil>) will always return false

Ladies and Gentleman,

I am struggling to rewrite the following code without isset any help would be highly appreciated.

<meta name="twitter:card" content="{{ cond (or (isset .Params.Twitter "image") (isset .Params.Image "src")) "summary_large_image" "summary"}}">

Why I need an alternative? Because I am getting the following warning in the console whenever I run the project.

WARNING: calling IsSet with unsupported type "invalid" (<nil>) will always return false.

Super thanks
