Currently when running sasjs request and the SAS program does not return a valid JSON response, the following appears in the console:

 ERROR  An error occurred while executing the request.
 The "data" argument must be of type string or an instance of Buffer, TypedArray, or DataView. Received undefined

Without a log, the above can be very difficult to debug. We should therefore enable a --log (or -l) flag (and print the location of the log in the console output).

The same logic can also be applied to the response json (with a -o or --output flag, same as sasjs job execute.

Functional Testing

The following should work:

create two test services using SAS Studio, eg:

filename mc url "https://raw.githubusercontent.com/sasjs/core/main/all.sas";
%inc mc;
filename ft15f001 temp;
parmcards4;
  %webout(OPEN)
  data fish;
    set sashelp.fish;
  run;
  %webout(OBJ,fish)
  %webout(CLOSE)
;;;;
%mp_createwebservice(path=/Public/app/adapter/test,name=fish)
parmcards4;
  %abort;
;;;;
%mp_createwebservice(path=/Public/app/adapter/test,name=err)

Execute the following command:

sasjs request /Public/app/adapter/test/fish

Expected:

No errors in console
sasjsbuild/output.json contains data
sasjsbuild/output.log contains log

Execute the following command:

sasjs request /Public/app/adapter/test/err

Expected:

Error in console
Log provided in sasjsbuild/output.log

Execute the following command:

sasjs request /Public/app/adapter/test/err -l ./mylog.txt

Expected:

Error in console
Log provided in ./mylog.txt

Execute the following command:

sasjs request /Public/app/adapter/test/fish -o ./data.json

Expected:

No errors in console
./data.json contains data
sasjsbuild/output.log contains log
[x] The -l flag works on both SAS 9 and Viya
[x] The -o flag works on both SAS 9 and Viya
[x] Tests are added
[x] The CLI docs are updated (both cli.sasjs.io and the terminal help)
[ ] The sasjs request video is re-recorded (Task for Allan)
