Logging from APIM to Event HUB seems not working properly

I've followed instructions in MS docs.

I've created an Event Hub namespace that hosts an hub called clicks-hub secured by a policy called ClicksLoggingPolicy with Send claim only.

Then I've added the logger to my APIM service using this URL: https://management.azure.com/subscriptions/MY_SUBS/resourceGroups/MY_RESGROUP/providers/Microsoft.ApiManagement/service/MY_APIM/loggers/clicksLogger?api-version=2019-12-01

with this payload:

{
    "properties": {
      "loggerType": "azureEventHub",
      "description": "Logger for click events",
      "credentials": {
        "name": "clicks-hub",
        "connectionString": "Endpoint=sb://myapim.servicebus.windows.net/;SharedAccessKeyName=ClicksLoggingPolicy;SharedAccessKey=****************"
      }
    }
}

After sending the PUT request I got 201 created.

I've configured an APIM API with this POST operation. It follows the XML policy:

<policies>
    <inbound>
        <log-to-eventhub logger-id="clicksLogger">@( "LOGGING_FROM_AZURE_APIM" )</log-to-eventhub>
        <mock-response status-code="200" content-type="application/json" />
        <base />
    </inbound>
    <backend>
        <base />
    </backend>
    <outbound>
        <base />
    </outbound>
    <on-error>
        <base />
    </on-error>
</policies>

I triggered various requests using the APIM Test panel and I can see requests on Metrics: enter image description here

but nothing where when I quert the hub:

SELECT
    *
INTO
    [OutputAlias]
FROM
    [clicks-hub]

enter image description here

I tried to ingest some test data using this tool and I can see the messages.

Any idea about what I'm missing?

Thanks in advance to anyone who'll try to help.

It seems you can only query when the EventHub message is an object / is JSON:

From this policy

<policies>
    <inbound>
        <log-to-eventhub logger-id="kai-logger">@( "LOGGING_FROM_AZURE_APIM1" )</log-to-eventhub>
        <log-to-eventhub logger-id="kai-logger">@( "{'message':'LOGGING_FROM_AZURE_APIM2'}" )</log-to-eventhub>
        <mock-response status-code="200" content-type="application/json" />
        <base />
    </inbound>
    <backend>
        <base />
    </backend>
    <outbound>
        <base />
    </outbound>
    <on-error>
        <base />
    </on-error>
</policies>

only the messages with LOGGING_FROM_AZURE_APIM2 show in the query.
