Why is my custom command to parse user agents in request and response returning the following " Search Factory: Unknown search command 'uaparser'" error?

[adari1990]

We have created a new custom command to parse user agents in request and response. It works perfectly in my local instance. But when I deploy in a distributed environment, we face the below error. It works when I use script uaparser fieldname on my search head but not with uaparser fieldname. I have deployed this on all search heads, Do I need to deploy on indexers as well?

[nw-splunkindx-201.dqs.test.com] Search Factory: Unknown search command 'uaparser'.

Yes, you probably need to deploy it too your indexers.
