Azure Logic App Upload Blob Trigger with Trigger Condition not fired

Question

I have an Azure Logic App (Standard) which is in a VNET integrated environment. I want to get triggered by an upload of a blob to a storage account with the following structure:

"containerName/SubFolder1/file.zrxp"

I need to use the Azure Blob Connector (in App)

I know that the connector gets only triggered if I choose as Blob Path the name of the container. Therefore I need to be sure, that the Logic App is only triggered, by a specific type of files with the ending "*.zrxp". So I wanted to use Trigger Conditions like this:

"triggers": {
            "When_a_blob_is_added_or_updated": {
                "conditions": [
                    {
                        "expression": "@endsWith(triggerBody()?['name'],'.zrxp')"
                    }
                ],
                "inputs": {
                    "parameters": {
                        "path": "containerName"
                    },
                    "serviceProviderConfiguration": {
                        "connectionName": "AzureBlob-4",
                        "operationId": "whenABlobIsAddedOrModified",
                        "serviceProviderId": "/serviceProviders/AzureBlob"
                    }
                },
                "type": "ServiceProvider"
            }
        }

But if I upload a file with this file ending to this container (containerName/SubFolder1), the workflow is not tiggered.

Any ideas what could be wrong?
