Access Database using Azure Functions #4437

amrsaafan created 6 years ago

Hello,

When trying to create Azure Functions that will access domain service at my system, domain service have methods that contact with database layer,

this is Code snippet of Azure function [attachment=2:1i2m5o8o]1.jpg[/attachment:1i2m5o8o]

This is the target method that should return all organizations: [attachment=1:1i2m5o8o]2.jpg[/attachment:1i2m5o8o]

And this is the exception: [attachment=0:1i2m5o8o]3.jpg[/attachment:1i2m5o8o]

there is an issue with the unit of work that we are creating it in the function, but that instance is not propagating down to the domain service like we expect.

Does the caller await this method?

Try removing the async Task declaration.

If the above does not work, please copy-and-paste the full stack trace.

unfortunately , removing the async Task declaration didn't resolve the problem So: the full stack trace.:point_down:

That doesn't look like the full stack trace.

hi,

I cannot view images clearly because they are tiny. And as @aaron stated, send the whole error message

It looks like you are using a pre-v2.1.0 version of ABP. Try upgrading to v2.3.0.
