Issue with Classification and Validation Process

[RPA_Dev13]

"Hi everyone,

I have the following scenario:

1. Dispatcher 1 reads the emails, saves attached files in a folder, and adds the invoice details to Q1.
2. Dispatcher 2 retrieves data from Q1, performs classification and validation and adds the validated invoice details to Q2.(Using Action Center)
3. The Performer retrieves data from Q2 and inserts it into the system.

The project was working perfectly, but today I encountered a problem: I can do classification but during the validation step I received the following error message.

I have an enterprise license.
