Do you know is this an issue on that promise? this is from the front-end cart component

Either a bug in the code or error in the docs. The code doesn't appear set up to actually return the line data 😕

haha Yeah, it would be great to update the doc since updating the code could take longer, but Yes it does not return anything, thanks Steve!

I will raise an issue with the team about it

by the way, the ideal solution would be returning the updating line, since each time an item is updated the internal line id is changed to something like:

item15188set179501

So, in order to update again an item we need to get that new line internal id based on the requirement.

OK, I have created an issue for you. Could you raise a case stating your problem and ask to have it associated with issue 586371, please

Sure, I can, thanks for your help! @Steve Goldberg
