Dataset refresh has stopped working with different errors each time I try to refresh

Hi Dale,

I am not using a data gateway, I am only connecting to an Azure Functions Proxy that connects to WorkflowMax API:

https://blog.kloud.com.au/2018/07/23/use-anonymous-authentication-on-web-data-sources-with-a-api-key-in-url/

At the point I wrote the blog everything was working fine, then I added the following changes to my data set:

1. I have a base data set that gets all the data from WorkflowMax/Proxy, so I created a new table based on this data set to get territory.

2. Then on the Job table I am doing a filtering on a column by using List.Contains from a Buffered List (To validate is an existing territory).  I basically load the territories on a buffered list to do the comparison, the territory list is not to big it has like 15 fields

So I don't know where the gateway error is coming from.

Many thanks
