Exception when reading JSON

Help Robot

Hello my name is Mario and I have a problem with an unnatended robot.

When I read JSON in a continuous iteration. The first read does it correctly but the following do not. Giving this error:

Server stack trace: at UiPath.Core.Activities.Retry.Do[ResultType](Func1 action, Int32 timeoutMS, Int32 retryCount) at UiPath.Core.Activities.ReadTextFile.ExecuteAsync(String fileName, String encodingStr) at UiPath.Core.Activities.ReadTextFile.<>c__DisplayClass12_0.<BeginExecute>b__0() at System.Runtime.Remoting.Messaging.StackBuilderSink._PrivateProcessMessage(IntPtr md, Object[] args, Object server, Object[]& outArgs) at System.Runtime.Remoting.Messaging.StackBuilderSink.AsyncProcessMessage(IMessage msg, IMessageSink replySink) Exception rethrown at [0]: at System.Runtime.Remoting.Proxies.RealProxy.EndInvokeHelper(Message reqMsg, Boolean bProxyCase) at System.Runtime.Remoting.Proxies.RemotingProxy.Invoke(Object NotUsed, MessageData& msgData) at System.Func1.EndInvoke(IAsyncResult result) at UiPath.Core.Activities.ReadTextFile.EndExecute(AsyncCodeActivityContext context, IAsyncResult result) at System.Activities.AsyncCodeActivity.System.Activities.IAsyncCodeActivity.FinishExecution(AsyncCodeActivityContext context, IAsyncResult result) at System.Activities.AsyncCodeActivity.CompleteAsyncCodeActivityData.CompleteAsyncCodeActivityWorkItem.Execute(ActivityExecutor executor, BookmarkManager bookmarkManager)

And finally only log write this: One or more errors ocurred. Why hapends?

Thx.

It is throwing file not found exception, can you make sure your file is available before reading ?

Of course, I check if file exists and then read it.
