Hello, I have a RESTLet that loads a search based on the params passed, and tries to send all the data of the search back. I tried passing multiple search ids to the RESTlet but I keep on getting the following error on different fields (custom as well as native). Is this something that needs to be fixed on the script or the field setup side?

"An nlobjSearchFilter contains an invalid operator, or is not in proper syntax: FIELD_ID."

sounds like you are constructing a filter incorrectly

Here it is:

function doGet(requestParams) {

        var results = [];
        var slice = [];
        var i = 0;

        var mySearch = search.load({
            id: requestParams.searchid
        });

        var resultSet = mySearch.run();

        do {
            slice = resultSet.getRange({ start: i, end: i + 999 });
            resultSet.forEach(function(row) {
                var resultObj = {};
                row.columns.forEach(function(column) {
                    resultObj[column.name] = row.getValue(column);
                    });
                results.push(resultObj);
                i++;
            });
        } while (slice.length >= 1000);

        return JSON.stringify(results);
    }

I wouldn't expect your code to actually return all the search results, your counting doesnt look right

Got it! It does look like the Integration Role does not have right permissions. Thank you!
