Alteryx Engine: Unable to create log file

7 - Meteor

I've created a workflow that runs macro1. Macro1 runs macro2, and macro2 runs macro3, etc. However, when macro2 tries to run macro3, alteryx throws the following error: "Alteryx Engine: Unable to create log file"


Is this a known issue? What is the solution for it?


Thanks in advance.

Hi Jo


from the message i see the logging directory pointing to a UNC path

Alteryx Engine: Unable to create log file "\\\CMPPBI\Alteryx Log Files\Current\Alteryx_Log_1452675344_1.log

is that correct ?


i suspect this could be an permission issue , but i think you dont need to provide the UNC path


for further troubleshooting, can you provide the screenshot of system settings. refer the below

The screenshots show both alteryx configuration menus, from server and designer.

can you change the Logging Path in User Settings to your Local Path and try (the One starts with \\londata002

Regrettably, it does not solve the issue.

The same log file is written by one workflow and there's a second workflow that tries to write to the same log file and fails.

Have any solutions been found for this?  I just started getting this error today from workflows that have been working fine for months.
