404 Resource not found in Power Apps but connector works in Power Automate

Posted on by NativeNass_ 223

Hi all

 

Getting quite annoyed here with the Power Platform 🙂

 

I have built a Custom Connector that connects to an OData web service URL.

 

I use the URL to get data and it needs a '$filter' parameter to fetch data based on a "No" value.

 

I have built the connector, My connector works perfectly fine in Power Automate, however, when I try to leverage this in Power Apps I get the following error;

My Powerapps formula looks like this;

When I go and look at the monitor, I see that my URL at the end is processed like this;

When I go and look at the test pane where I built my custom connector, the Request URL looks like this;

Btw, the testing of the custom connector works perfectly fine.

These 2 already don't seem to add up.

 

 

My base request URL in the custom connector wizard is this

With the following query

Anybody got some experiences with this?

 

This is not behaviour one should expect...

 

Thanks in advance

    Thanks for the input, however, nothing seems to work as expected.
    I have tried almost everything. The fact that it's as 'strange' as it is today doesn't convince me to use something like this in a production environment.

     

    Could be wrong here from my side but it shouldn't need specific workarounds like this.

    There is also a problem in custom connectors that occurs when using it in Power apps because Power apps tries to encode the spaces, you can try to replace spaces with +

    Can you try passing the filter like this:  . GetCustomer({$filter:"No+eq+'123'"})

     

    I don't think you need quotes around $filter, but if the above doesn't work try with quotes as well. GetCustomer({'$filter':"sa+as+='asd'"})

    Hi @NativeNass_  I believe that you don't have to send it  as an object from PowerApps when it is a query parameter, you specify it as a value, in your case, it would be .GetCustomer("No eq 'xxx'")
