ScriptRunner: Table Grid Data returning empty result?

[Aira Veronica Dizon]

Hello,

My goal is to read grid data values, however my script is returning an empty grid result even though my grid has values in it. This is the error I'm getting:

"Grid ID 11234 data cannot be retrieved [] Grid ID 11234 content []"

Here is my script:

throw invalidInputException;

}
}

println(result.toString());
return result.toString();
