CPYTOIMPF fails mysteriously

The command

CPYTOIMPF FROMFILE(FOO/BAR *ALL) TOSTMF('/home/JWOEHR/foobar.csv')
RCDDLM(*CRLF) ADDCOLNAM(*SQL)

and every variation thereof I have tried fails as follows:

Message ID . . . . . . : CPC2957 Severity . . . . . . . : 00

Message type . . . . . : Completion

Date sent . . . . . . : 06/20/19 Time sent . . . . . . :
10:06:08


Message . . . . : No records copied from file BAR in FOO.
Cause . . . . . : No records were copied from member or label BAR in
file BAR in library FOO because the from-file member or label did not
contain records or records did not meet the selection requirements.

Technical description . . . . . . . . : If the from-file or to-file
member
or label name is *N, the file is a printer, nonlabeled tape, or a inline

data file. If the from-file library name is *N, the file is a inline data

file. Records are copied based on the following selection requirements:

-- For CPYF command, character values specified on the INCCHAR
parameter.
-- For CPYF command, field values specified on the INCREL parameter.

-- For CPYFRMQRYF command, query selection specified on the OPNQRYF

command.


This seems to be complete nonsense. Everything exists. Any tips?
