eventhub.Receive function gives no such file or directory instead of creating one

[sariburak]

Setup

I first create a FilePersister and Hub by the following code:

persister, err := persist.NewFilePersister(output)
if err != nil {
	// error handle
}
hub, err := eventhub.NewHubFromConnectionString(conn_str, eventhub.HubWithOffsetPersistence(persister))
if err != nil {
	//error handle
}
t.hub = hub

and then try to fetch data from EventHub like this:

for _, partitionID := range partitionIDs {
    _, err := t.hub.Receive(ctx, partitionID, handler, eventhub.ReceiveWithConsumerGroup('$Default'))
    if err != nil {
        // err handle
    }
}

However. hub.Receive gives no such file or directory error.

Expected Behavior

FilePersister file should be automatically created.

Actual Behavior

gives no such file or directory error.

Environment

• OS: macOS Ventura
• Go version: go version go1.19.1 darwin/arm64
• Version of Library: 3.3.20

Additional Notes

I tried to run the code in a docker container. I built the code and copied the binary into a docker container which is running on golang:alpine. In that case, code run without any problems. So that's interesting.

Also, in my local run, I am sure the output dir has all the permission it needs.
