Updating layer on lambda fails sometimes due to function update process not finished (?)

[martinbaste]

Symptoms:

The workflow fails sometimes (not always) with this error:

Using the layer in the function...

An error occurred (ResourceConflictException) when calling the UpdateFunctionConfiguration operation: The operation cannot be performed at this time. An update is in progress for resource: [functionARN]

And this happens just after the function code is updated, so I imagine that it is caused by the process trying to update the layer while the function is still updating.

Maybe it would be possible to retry or wait a couple seconds?

Was running into this, too. For anyone else that lands here, try this fork of the action: NicPWNs/py-lambda-action@main.
