Hi all, in the fundamentals capstone 1.5 we are asked to run an API by connecting to a port. in 1.4 i assigned the variable as required:

refServiceHandle: hopen 5010

so in 1.5, so run the API in question on the uniqueOpts variable, i run’

refServiceHandle “getOptionsRef[uniqueOpts]”

and i get an error in kx developer that just says uniqueOpts. Can I ask what mistake am i making? thank you &nbsp;

to pass parameters over IPC try calling using parenthesis instead of inside quotations

refServiceHandle(`getOptionRef;uniqueOpts)
