AttributeError: 'Registry' object has no attribute 'resolving'. Did you mean: 'resolver'? #1352
Description
I am making test code that validates JSON by schema. When I run it, the error occurs:
AttributeError: 'Registry' object has no attribute 'resolving'. Did you mean: 'resolver'?
Is it the library issue or do I do something wrong?
Code:
import json
import jsonschema
import referencing
def main():
with open('data.json', 'r') as f:
json_data = json.load(f)
with open('schema.json', 'r') as f:
json_schema = json.load(f)
print("Json data:", json_data, sep='\n')
res = referencing.Resource.from_contents(json_schema)
reg = referencing.Registry().with_resource(res.id(), res).crawl()
jsonschema.validate(json_data,
reg["https://t1m013y.github.io/jsonschema/test_person"].contents,
None,
reg)
if __name__ == '__main__':
main()schema.json:
{
"$schema": "https://json-schema.org/draft/2020-12/schema",
"$id": "https://t1m013y.github.io/jsonschema/test001.json",

}
}
}
}data.json:
{
"name": "John",
"age": 3

You want the
registryargument, not the deprecated resolver argument which is what you're getting by passing the registry positionally like that.Specifically you want:
