Observed Behavior

Processes using large amount of data (e.g. Excel files with more than ~2500 rows) can fail with the following error:

Message: Could not retrieve the result of the job execution. This might be because a message was too large to process.
Exception Type: System.Exception

Cause

The output of the job execution exceeds the maximum configured value of the maxMessageSizeInMegabytes parameter in the uipath.config file.

This parameter has a default value of 10 MB.

Based on the deployment, the uipath.config file can be found in the following locations:

• When installed with the MSI: C:\Program Files (x86)\UiPath
• When installed with the Exe: %localappdata%\UiPath

Solution

Increase the value of the maxMessageSizeInMegabytes parameter in the uipath.config file to a greater value such as 50 MB.
