Right now using WebAPI requests (retrieveRecord, createRecord, ...) or Utility.getEntityMetadata pcf-sdk requests inside harness fails.
I can understand why, but this will make harder to make real development/testing inside harness.
There is already an idea about dataset harness sample data: https://powerusers.microsoft.com/t5/PowerApps-Ideas/Allow-sample-data-for-DataSet-component-in-harness-pcf-start/idi-p/292499
Would it be possible to allow us to define some sample data for the webAPI requests? That would allow us to make also some unitests.
Or maybe we could configure a connection to CRM/CDS, where this requests could take the data inside harness too?
Is there another way to work arround this problem?
