How to use JSON extracted fields with eval function typeof?

Path Finder

When I try to do anything with the JSON fields extracted during data input, I get things like Invalid when I do typeof in an eval. I can see the extracted fields in the UI and the Timestamp is correctly used. I have tried the following:
sourcetype=json | eval myField=typeof(LogEntry.Content.Amdps1204ipmCpy.Dps1204Ipm.HeaderSegmentGrp.CreationDate)
which is clearly a string, but returns Invalid. I cannot execute a strptime on it either.

I have the following as an example of JSON log data. According to the JSONLint validator, it is a valid JSON message.

Re: How to use JSON extracted fields with eval function typeof?

OK. In order to use the JSON field, it has to be in single quotes. The following work:
sourcetype=json | eval myField=typeof('LogEntry.Content.Amdps1204ipmCpy.Dps1204Ipm.HeaderSegmentGrp.CreationDate')
sourcetype=json | eval myField=strptime('LogEntry.Content.Amdps1204ipmCpy.Dps1204Ipm.HeaderSegmentGrp.CreationDate', "%a %b %d %H:%M:%S %Z %Y")
