PowerApps and Epicor

Epicor ERP 10

I have run sort of stuck on something i have been trying out. Hoping maybe someone here might be able to point out what i am doing wrong.

So I have started to play around with PowerApps and I want to have it access our Epicor to pull some simple data via REST. We are running 10.2.400.23 onprem.

I have installed a MS Gateway.

I have created a SQL connector. Works great. I can create a PowerApp that can pull data from the Epicor DB. cool but i want REST.

I have created a custom connector that uses REST to get the list of all customers from the Training environment. (https://ourserver/epicortrain10/api/v1/Erp.BO.CustomerSvc/Customers).

In the Custom Connector, i can validate it and test it. It pulls all the customers into a json object. cool!

Now for where i am stuck. I create a new PowerApp. I add the connector as a data source to the app. I create a gallery object with the datasource as the connector using the GETCUSTOMERS call.

The issue i have is that is always says 'We didn’t find any data".

This shows it can see the schema:

But i just can’t seem to get any data.

Anyone else out there created a PowerApp using the gateway to communicate with Epicor? Any help is greatly appreciated.

what does IIS log show on the server you call here? do you have this call there, what is the return http code?

Yes, this call is there:

2020-06-01 14:26:37 X.X.X.X GET /epicortrain10/api/v1/Erp.BO.CustomerSvc/Customers - 443 - X.X.X.X Mozilla/5.0+(Windows+NT+10.0;+Win64;+x64)+AppleWebKit/537.36+(KHTML,+like+Gecko)+Chrome/83.0.4103.61+Safari/537.36 https://us.create.powerapps.com/studio/ 200 0 0 413

Does the call uses correct company? Check Ice.SysUserFile table field CurComp for the user you log in.

I eventually did get my PowerApp to work, pulling information from Epicor via REST however I found i was not able to create the custom connector in PowerApps that would get what i needed from Epicor. As mentioned above, it was always empty. I just could not figure out why.

What i did get to work however was to first create the request and examples using Postman. I then exported the collection out of Postman and there happens to be an option in the Microsoft PowerApp environment to import a Postman collection as a custom connector.

Bingo! that worked. But, even setting up my custom connector by hand copying everything i could see from what MS did by importing the Postman collection, i still couldn’t get it to work. no idea…

So, in the end, i started to do all my work in postman and then exported the collection out and into MS to get what i needed. PowerApp created.

So what did I learn from all of this? Yes, i can create a PowerApp to pull simple information from Epicor but … doing even the simplest thing seemed very problematic, buggy, and just mind boggling confusing. I took a different route and found creating my own custom app (as mentioned here:Epicor Rest Helper (Nuget) Updated (1.1.11)) to be much simpler.

I had such high hopes for PowerApps. :disappointed:

weird :confused:, I wonder if they have logging for that to troubleshoot.
Also I would try some smaller amount of data. probably by adding $top and $select.
