Yes but before going to RFC details one should check the basic spelling and
syntax first...
if there was a spelling mistake, the error would not be "CNAME and other data"
when the error is "CNAME and other data", spelling mistakes don't matter...

CNAME records cannot coexist with any other records last time I’ve
checked. See section 2.4 from RFC1912[1]
[1] https://tools.ietf.org/html/rfc1912
Well it actually goes back to RFC 1034. Unfortunately it wasn’t enforced in
nameservers at the beginning and is still not enforced by some servers.
3.6.2. Aliases and canonical names
...
The domain system provides such a feature using the canonical name
(CNAME) RR. A CNAME RR identifies its owner name as an alias, and specifies
the corresponding canonical name in the RDATA section of the RR. If a CNAME RR
is present at a node, no other data should be present; this ensures that the
data for a canonical name and its aliases cannot be different. This rule also
insures that a cached CNAME can be used without checking with an authoritative
server for other RR types.
