Topic

In case the Get Email Dac Command fails intermittently with the Robot but works with the studio and if you notice the error from the Player Logs below


System.IO.FileLoadException: Could not load file or assembly 'Microsoft.Extensions.Caching.Memory, Version=6.0.0.2'


This indicates a version mismatch or dependency issue with the caching library used by the RuntimeCache service.

Please try the following instructions to reduce the occurrence of the problem.


Instructions 

Reduce the frequency of email triggers being sent to the robot/studio.

Allow a longer delay between email batches (for example, waiting approximately 5 minutes between each batch).

This spacing has been observed to improve reliability and reduce the number of caching-related errors.
