Virtual agent error

[nicolas90]

Hello

I'am new in serviceNow development program and i'm facing an issue with virtual agent.
Below my project :
I would like to use the VA UI to get user questions and in the background use an API to get answer with a Q&A tools with GPT.
So the workflow is : User input through VA > Use a Topic Block to Call REST > REST Call to my API > Response from API > VA write back answer to the user.

I know it's working because i can use it on a fresh Dev instance of a collegue, but it do not works on mine where we have a few developments that i would love not to loose them !

I probably made a miss configuration somewhere !

I have attached error message when i tried from the topic block test, but the virtuall agent flow and the rest message is working when i test them separetly

Can some one coud help me on that subject ?

Here the last error message from the VA : 

• 00:37:05.696 Topic Node Script Error at topic [_PRVW__9ecf91f6d919f150da2df3317ad39f5d], at variable [vaInputs.__silent_FDIHInvocation_a4a509f1d6a54814986db90dc733ddfe], for task [b7cfd17a0715f150b1a9f1e08c1ed012], expression: [vaVars.previous_graph_node="AskQA___a4a509f1d6a54814986db90dc733ddfe";var ackMsg=null;ackMsg=(function execute() {var inputs = {};inputs[prompt] = vaInputs.query.getValue();var outputs = {"answer":"string","don_t_treat_as_error":"boolean","action_status":"object"};var outputParamNameToTopicVarExpr = {"answer":"answer","__dont_treat_as_error__":"don_t_treat_as_error","__action_status__":"action_status"};vaVars._current_fdih_contextId=vaSystem.waitForResponseFromFDIHAction_2(global.questionanswering, inputs, outputs, outputParamNameToTopicVarExpr, 2eaee3bb07ac7d10b1a9f1e08c1ed039, true);})();null;vaInputs.query.reset();vaVars.__suspendable__semaphore_a4a509f1d6a54814986db90dc733ddfe=released;(function() {vaInputs.query.reset();})();ackMsg;], error [org.mozilla.javascript.JavaScriptException: java.lang.RuntimeException: Error calling FDIH (wait for response) actionglobal.questionanswering,'
  
  
  It looks like a java.lang.RuntimeException thrown during waitForResponseFromFDIHAction_2  ? But i have no idea how to fix it.

Had similar issue with "java.lang.RuntimeException: Error calling FDIH" when trying to use action in VA. Recreating action in flow solved the problem
