When using "typeof, results are field value invalid

[vsid_splunk]

I have used "typeof" to know the Types for fields for the data set in splunk web version, but I get the Value column showing invalid in each one of its corresponding rows.

@vsid_splunk  try putting single quotes around the field name that is returning as invalid.

@somesoni2 can you look at my search, sir?

[vsid_splunk]

sourcetype = json | FieldsTypes

This macro definition of FieldsTypes is.... eval Ent_Code = typeof ('TableEntry.EventCode')

So @somesoni2 , im seeing the Ent_Code as invalid in "value" column after I click on "AllFields"

[somesoni2]

Can you post your search?
