This happens if you set context = "some string value". context is defined as type = any because it has been around since before Terraform had types and we want it to be as compatible as possible with various Terraform versions. However, it actually is required to be an object, which you would get from the output of another null-label module. You can infer the full definition of the object from the default value:

terraform-null-label/variables.tf

Lines 3 to 28 in 38187a0

	default = {
	enabled = true
	namespace = null
	tenant = null
	environment = null
	stage = null
	name = null
	delimiter = null
	attributes = []
	tags = {}
	additional_tag_map = {}
	regex_replace_chars = null
	label_order = []
	id_length_limit = null
	label_key_case = null
	label_value_case = null
	descriptor_formats = {}
	# Note: we have to use [] instead of null for unset lists due to
	# https://github.com/hashicorp/terraform/issues/28137
	# which was not fixed until Terraform 1.0.0,
	# but we want the default to be all the labels in `label_order`
	# and we want users to be able to prevent all tag generation
	# by setting `labels_as_tags` to `[]`, so we need
	# a different sentinel to indicate "default"
	labels_as_tags = ["unset"]
	}

Closing as invalid.
