I was about to report a bug about this:

Looks like RSEAPI server sent a 200 response but the payload is not a list of member but an warn or error message which zowe explorer parses as those two members.

The weirdest thing is that if I execute using swagger I receive an empty JSON response but the PDS does have a member:

I can see the member in ISPF panel:

However I can notice that "size" is empty while the member does have two lines:

So it seems that zowe explorer is not the one to blame but I see nowhere any indication of failure in RSEAPI process log neither in zowe explorer output window.

Have you ever seen something like this?

Where I could fill a bug report for RSEAPI?

FWIW:
