Hi - I'm an old dev just getting into Umbraco (V13). I'm working through the tutorials in the docs but have got a bit stuck on this one: https://docs.umbraco.com/umbraco-cms/tutorials/creating-a-property-editor/part-4 It has code for a resource that wraps a call to an api in umbRequestHelper.resourcePromise. I have found that if I just copy this code, there are no errors, but do data is returned to the view. If I take the API call out of umbRequestHelper.resourcePromise then everything is good. What am I missing? And are there any resources anyone can recommend to accelerate my learning? Many thanks!
