Description
I made a mistake in my schema and had "format": ["date", "datetime"], which is invalid.
I tried to validate my schema against the official JSON schema for JSON schema: http://json-schema.org/draft/2019-09/schema but jsonschema did not complain:
$ jsonschema -i test-schema.json json-schema.schema.json ; echo $?
0
My test schema:
{
"$schema": "http://json-schema.org/draft-07/schema#",
"type": "object",
"properties": {
"foo": {
"type": "array",
"items": {
"type": "string",
"format": ["date", "datetime"]
}
}
}
}
jsonschema should complain about that format not being a string.
The (not understandable for me) error I got was:
$ jsonschema -i test-data.json test-schema.json
Traceback (most recent call last):
