Cannot add a dataflow to a gateway

Hi Zoe Zhi,

I assume I would have to add that test sql  database to my gateway as a connection right? 

For my dataflow, I'm not trying to connect to a sql database. I'm trying to use a Web connection to make an API call to my system. I typically do all of my configurations to my data in Power BI desktop > copy the M code from the query > paste it as a blank query in the dataflow creation on the web. This has worked perfectly for me in the past with no issues. Now, over the past few weeks I've been running into these issues that prevent me from creating or adding to my existing dataflows. The dataflows I created months ago still work fine but I'm unable to make new ones. I should also add that only new dataflows I create do not allow me to edit the gateway information for them. All of the existing dataflows allow me to change the gateway information.

I'm hoping someone has a fix or this is a known issue becuase I shouldn't have to backdoor basic functionality.
