ecl run does not support MACROs or FUNCTIONs

It appears that ecl run does not support running MACROs or FUNCTIONs.
 
I have simplified the code for this Jira:

Macro
//echoTest1.ecl
EXPORT echoTest1(inVal='hello world') := MACRO
 OUTPUT(inVal);

ENDMACRO;

then: 

ecl run hthor "C:\Users\Public\Documents\HPCC Systems\ECL\My Files\MyProgrammersGuide\echoTest1.ecl" --input "<request><inVal>'gbye'</inVal></request>" --ecl-only
 
 
W20211202-151145
   state: failed
 
eclcc: (1,0): Error C3: Query is empty

1 error(s), 0 warning(s)
 
Function
//echoTest2.ecl
EXPORT echoTest2(STRING inVal='hello world') := FUNCTION
RETURN OUTPUT(inVal);

END;

then: 

C:\Program Files (x86)\HPCCSystems\8.4.0\clienttools\bin>ecl run hthor "C:\Users\Public\Documents\HPCC Systems\ECL\My Files\MyProgrammersGuide\echoTest2.ecl" --input "<request><inVal>'gbye'</inVal></request>" --ecl-only
