POS: Product availability panel stopped working (error)
Description
There are multiple extension samples provided by Microsoft together with POS solution. One of them is ‘Product availability’ panel that displays real-time stock level of the product.
After retail update to 7.3.11971.64069 version ‘Product availability’ panel stopped working – started to display error.
Let’s find out what is wrong and how we can fix the panel.
Why issue happens
‘Product availability’ sample was not changed to become compatible with a new version of ‘Product availability’ functionality on Retail server. As the result, Retail server throws the following exception:
An error occurred while trying to send all bufferred output to the client. Exception: System.Collections.Generic.KeyNotFoundException:
The given key was not present in the dictionary.
at System.ThrowHelper.ThrowKeyNotFoundException()
at System.Collections.Generic.Dictionary2.get_Item(TKey key)
at Microsoft.Dynamics.Retail.RetailServerLibrary.ODataControllers.OrgUnitsController.SearchProductAvailability(ODataActionParameters parameters, ODataQueryOptions`1 queryOptions)
at lambda_method(Closure , Object , Object[] )
Error from Fiddler:
“TypeName”: “CommerceException”,
“Exception”: “{\r\n \”ErrorResourceId\”: \”Microsoft_Dynamics_Internal_Server_Error\”,\r\n \”LocalizedMessage\”: \”Beim Verarbeiten dieser Anforderung ist ein Fehler auf dem Server aufgetreten.\”\r\n}
What parameters are required by Retail server
Look through retail server metadata: searchProductAvailability function requires 2 parameters: productId and orgUnitAvailabilitySearchCriteria
<Action Name="SearchProductAvailability" IsBound="true">
<Parameter Name="bindingParameter" Type="Collection(Microsoft.Dynamics.Commerce.Runtime.DataModel.OrgUnit)"/>
<Parameter Name="productId" Nullable="false" Type="Edm.Int64"/>
<Parameter Name="orgUnitAvailabilitySearchCriteria" Type="Microsoft.Dynamics.Commerce.Runtime.DataModel.OrgUnitAvailabilitySearchCriteria"/>
<ReturnType Type="Collection(Microsoft.Dynamics.Commerce.Runtime.DataModel.OrgUnitAvailability)"/>
</Action>

How CPOS request to Retail server looks now
CPOS request to retail server contains only one parameter – productId, that causes the issue.
let request: InventoryLookupOperationRequest<InventoryLookupOperationResponse> =
new InventoryLookupOperationRequest<InventoryLookupOperationResponse>
(this._state.product.RecordId, correlationId);
How CPOS request should look like
Add the parameter orgUnitSearchCriteria to CPOS request – and the issue will be fixed, ‘Product availability’ panel will work well.
var orgUnitSearchCriteria = new ProxyEntities.OrgUnitAvailabilitySearchCriteriaClass
let request: InventoryLookupOperationRequest<InventoryLookupOperationResponse> =
new InventoryLookupOperationRequest<InventoryLookupOperationResponse>
(this._state.product.RecordId, correlationId, orgUnitSearchCriteria);
