Parameters

It is possible to get some errors depends on how long query in your URL. It is not a good idea to have such long values in a query. And such value should be escaped to be valid to place in URL. Instead much better to send data as a form in POST.

Your query parameter is getting mapped to a property in the class, and the default maximum length for string properties is 50 characters. You will need to explicitly set a different MAXLEN for that property if you want it to hold longer strings:

Parameter Name As %String(MAXLEN = 100, ZENURL = "name");
