ERROR: "Invalid key in stanza [x] in "

Applicability

Splunk Enterprise

Description

This kind of errors are normally related to attributes not defined in the Splunk documentation, could appear after doing an upgrade or implementing new changes.
 

Investigation

The first thing to do here will be to identify the value keys (attributes) that the error is appointing to, e.g.:
 

Invalid key in stanza [email] in /opt/splunk/etc/system/local/alert_actions.conf, line 4: 
reportServerURL

In this case the same error is indicating that the reportServerURL is the attribute that produces the error below the stanza [email] and this is located in the file "/opt/splunk/etc/system/local/alert_actions.conf".

To validate if an attribute is valid by looking at the official Splunk documentation, in this case, go to the alert_actions.conf documentation and see that the attribute reportServerURL is not valid.
 

Resolution

In order to make these errors disappear, go into the specified .conf file, below the stanza the error is mentioning and then erase the invalid attributes.

Using the "#" symbol to comment out the line also resolves the issue.

 

NOTE: Remember to restart Splunk after doing any change in the configuration files.
