I am working with an OOB Virtual Agent, I've enabled AI Search within it but it appears that it is not passing the search value or some other error causing no result.
I get the "I'm having technical issues and won't be able to continue this conversation" error when attempting to search within the Virtual Agent.
When I try in Flow Designer and check the AI Search action I get "Error: Empty JSON string,Detail: Empty JSON string"
Below is the log:
Encountered error executing instruction: OpInstruction{id=1, opClass=com.snc.process_flow.operation.script.ScriptOperation, io=Io{input={mid_selection=RefOrValue{value=auto_select, isRef=false}, capabilities=RefOrValue{value=, isRef=false}, mid_server=RefOrValue{value=, isRef=false}, mid_cluster=RefOrValue{value=, isRef=false}, mid_selection_type=RefOrValue{value=any, isRef=false}, additional_context=RefOrValue{value=in.additional_context, isRef=true}, search_context_id=RefOrValue{value=in.search_context_id, isRef=true}, locale=RefOrValue{value=in.locale, isRef=true}, script=RefOrValue{value=(function execute(inputs, outputs) {
var context = JSON.parse(inputs.logging_context);
var actionStartTime = new GlideDateTime().getNumericValue() - parseInt(inputs.start_time);
var logger = VAAISearchHelper.getLogger(context);
gs.log('AI Search FDIH action started: {0}ms', actionStartTime);
try {
// Log all inputs
gs.log('Inputs: {0}', JSON.stringify(inputs));
// Retrieve search results
var api = new AISearchRetrieveSearchResultsWrapper();
var searchResult = api.retrieveSearchResults(inputs.search_term, inputs.context_profile_id, inputs.search_context_id,
inputs.logging_context, inputs.locale, inputs.additional_context);
// Log the API response
gs.log('API Response: {0}', searchResult);
// Check if searchResult is empty or invalid JSON
if (!searchResult) {
throw new Error("Empty response from API");
}
outputs.search_results = JSON.parse(searchResult);
} catch (ex) {
gs.log("Error retrieving search results: {0}", ex.toString());

I tried adding some logging into the AI Search Action but was unable to find any further information.

The utterance is hitting AI Search - Fallback but not AI Search is the best I can figure out as to the why, but the how/how to fix is not something I've been able to drill into.
