This is very common behavior. This is where a good manager can really help. They can recognize this is happening and then provide context.

One approach to deal with ambiguity is to write a short design doc, which writes down what you are trying to do, and all of the assumptions that you are making. If you don't understand the domain, some of your assumptions will probably be wrong. The stakeholder should be able to see that and provide guidance.
