`yaml.ConfigGroup` raises exception when run with Pulumi 3.4.0 under Python

See original GitHub issue

When running with Pulumi 3.4.0 on Python, trying to create a yaml.ConfigGroup fails with an exception in the ConfigGroup constructor. Downgrading to Pulumi 3.3.1 fixes the issue, which suggests pulumi/pulumi#7175 may be related.

Steps to reproduce

Create a ConfigGroup:

__main__.py:

"""A Kubernetes Python Pulumi program"""

import pulumi
from pulumi_kubernetes.yaml import ConfigGroup

CONFIGS = [
    """
apiVersion: v1
kind: Namespace
metadata:
  name: java
    """.strip(),
    """
apiVersion: v1
kind: Namespace
metadata:
  name: chesterfield-kings
    """.strip(),
]

config_group = ConfigGroup("configs", yaml=CONFIGS)

pulumi preview

Expected: The preview runs successfully and previews creating the two namespaces. Actual:

error: Program failed with an unhandled exception:
error: Traceback (most recent call last):
  File "/pulumi/bin/pulumi-language-python-exec", line 92, in <module>
    loop.run_until_complete(coro)

  File "/usr/local/lib/python3.8/site-packages/pulumi/output.py", line 157, in run
    value = await self._future

    transformed: Input[U] = func(value)
  File "/usr/local/lib/python3.8/site-packages/pulumi_kubernetes/yaml.py", line 190, in <lambda>
    self.resources = pulumi.Output.all(resources, self.resources).apply(lambda x: {**x[0], **x[1]})
TypeError: 'list' object is not a mapping
