>>> errcode $CLI bundle validate -o json --target invalid_json

=== file has wrong structure
>>> errcode $CLI bundle validate -o json --target wrong_file_structure
Error: failed to parse variables file $TMPDIR/.databricks/bundle/wrong_file_structure/variable-overrides.json: invalid format

Variables file must be a JSON object with the following format:
{"var1": "value1", "var2": "value2"}

=== file has variable that is complex but default is string
>>> errcode $CLI bundle validate -o json --target complex_to_string
Error: variable cluster_key is not of type complex, but the value in the variable file is a complex type

=== variable is required but it's not provided in the file
>>> errcode $CLI bundle validate -o json --target without_defaults
Error: no value assigned to required variable cluster. Assignment can be done using "--var", by setting the BUNDLE_VAR_cluster environment variable, or in .databricks/bundle/<target>/variable-overrides.json file
