StringParameter.from_string_parameter_attributes returns 'Resource' instead of 'IStringParameter'

[Marty-Me]

After the 1.16.0 release of this morning the synthesizing of our infrastructure started failing.
It seems like the StringParameter.from_string_parameter_attributes method provides the wrong return type (it states IStringParameter but the actual type is Resource.

Reproduction Steps

from aws_cdk import core
from aws_cdk.aws_ssm import StringParameter
from aws_cdk.core import Stack

APP = core.App()

STACK_WITH_ISSUE = Stack(APP, 'StackWithIssue')
FAILING_SSM_PARAMETER = StringParameter.from_string_parameter_attributes(STACK_WITH_ISSUE, 'FailingSSMParameter',
                                                                         parameter_name='param-name')

print(FAILING_SSM_PARAMETER)
print(FAILING_SSM_PARAMETER.string_value)

APP.synth()

Error Log

<aws_cdk.core.Resource object at 0x1103cf9d0>
Traceback (most recent call last):
  File "infrastructure/IssueStack.py", line 12, in <module>
    print(FAILING_SSM_PARAMETER.string_value)
AttributeError: 'Resource' object has no attribute 'string_value'

A temporary fix is using:

FAILING_SSM_PARAMETER._physical_name

[skinny85]

Could this be a different manifestation of this: #4966 ?

[RomainMuller]

Definitely is.
