The timestamp parameter is not optional

[timmattison]

This code says that the timestamp value is optional but if I leave it out it always fails with the errors below.

The Greengrass model code is here -

aws-iot-device-sdk-python-v2/awsiot/greengrasscoreipc/model.py

Line 2581 in 6a6e634

self.timestamp = timestamp # type: typing.Optional[datetime.datetime]

The logs are:

If I specify a timestamp it works as expected.

Does only happen with UpdateConfigurationRequest?

Can you provide a minimal code example that reproduces this?

Hi @jmklix - I've also had the same problem, it only appears to be an issue with the UpdateConfigurationRequest model in my testing. Here's a minimal code example:

update_config_request = UpdateConfigurationRequest()
update_config_request.key_path = keyPath
update_config_request.value_to_merge = valueToMerge

op = ipc_client.new_update_configuration()
op.activate(update_config_request)
fut = op.get_response()

result = fut.result(TIMEOUT)
return result

Interestingly, even specifying a datetime object for the UpdateConfigurationRequest.timestamp property gives me this error: TypeError: descriptor 'timestamp' of 'datetime.datetime' object needs an argument.

The only way I was able to fix this was to create a new class that inherits from UpdateConfigurationRequest, then assign a float epoch time using time.time().

[timmattison]

This is a much better response than I would've given. Do you need anything else to work on this?

A recent model update and client regeneration looks to have fixed this issue.
