Thank you for your help.
Sorry for the confusion. I'm not a native English speaker.
Yes, I'm not referring to automate, but rather a code in powerApp.
What I meant by "1 in 1000 execution that failed" was an estimate of how many times this failure happens, for example if this code is executed 5000 times by my clients, I will have this problem around 5 times or more.
For CadRU I can confirm that the line exists and had a status of "Pendente", since several other validations carried out before this depend on this information.
Whenever I notice the error, I rerun the code to redo the validations and it runs normally.
As for FilaContagemRecomendacao, I can guarantee that it was not executed. Hence the concern.
I really believe it is an internet failure, as these errors are always with users of a specific company. But I'm investigating whether there is anything else that could cause this failure just to be safe.
