ServiceBusSessionMessageActions not working with IsBatched=true

[Meorir]

Description

When trying to bind
ServiceBusSessionMessageActions sessionActions

while having IsBatched = true

causes this error:
Result: Function 'ServiceBusHandler', Invocation id '5dae4abd-65bf-434d-97f9-ad28900a6c2d': An exception was thrown by the invocation. Exception: Microsoft.Azure.Functions.Worker.FunctionInputConverterException: Error converting 1 input parameters for Function 'ServiceBusHandler': Cannot convert input parameter 'sessionActions' to type 'Microsoft.Azure.Functions.Worker.ServiceBusSessionMessageActions' from type 'System.String'. Error:System.InvalidOperationException: Expecting SessionId within binding data and value was not present. Sessions must be enabled when binding to ServiceBusSessionMessageActions.

I assume batch processing in session enabled subscription (or queue) should be locked to a single session per invocation due to session locks.

[Function("ServiceBusHandler")]
public async Task ServiceBusHandler(
[ServiceBusTrigger("%ServiceBusTopicName%",
"%ServiceBusSubscriptionName%",
Connection = "ServiceBusConnectionString",
IsSessionsEnabled = true,
AutoCompleteMessages = false,
IsBatched = true)]
ServiceBusReceivedMessage[] messages,
ServiceBusMessageActions messageActions,
ServiceBusSessionMessageActions sessionActions
)

When using with single message everything works fine.
(except SetSessionStateAsync not accepting null as parameter, and not allowing to clear session state, but that is another bug)

Steps to reproduce

Create a trigger for session-enabled ASB subscription:

[Function("ServiceBusHandler")]
public async Task ServiceBusHandler(
[ServiceBusTrigger("%ServiceBusTopicName%",
"%ServiceBusSubscriptionName%",
Connection = "ServiceBusConnectionString",
IsSessionsEnabled = true,
AutoCompleteMessages = false,
IsBatched = true)]
ServiceBusReceivedMessage[] messages,
ServiceBusMessageActions messageActions,
ServiceBusSessionMessageActions sessionActions
)

After invocation the mapping throws an error

@Meorir please see the issue I duplicated this to - you are experiencing the same problem, source gen is not running for your project.

Re-opening, looked into this a bit more and I think there is a gap with batched receive and ServiceBusSessionMessageActions

[jviau]

@Meorir I have identified a gap in our binding support here. Combining session, batch, and ServiceBusSessionMessageActions is not currently supported, leading to the issue you see. For now, you can use ServiceBusSessionMessageActions if you remove the batched behavior from your trigger. We will use this issue to track adding batch support to this area.

Issue

ServiceBusSessionMessageActionsConverter says it supports ServiceBusSessionMessageActions[], however its implementation does not correctly bind to an array.
