Doesn't work correctly request filter 'allpages'

Hello Team,

According to the Sage 300 specification, we can use the following filter 'allpages'
For example:

http://{ip adress}/Sage300WebApi/v1.0/-/SAMLTD/AR/ARCustomers?$inlinecount=allpages

But, we cannot receive the number of customers in the response.
What is the correct expected result for this request?
What we should receive using this request?
