Handling Validation Errors

Invalid Data Examples​

Missing Required Field​

{
"insert": {
"id": "ex:people/invalid",
"type": "ex:Person",
"schema:givenName": "Bob"
}
}

Error: "Must have a valid email address"

Invalid Value Range​

"id": "ex:people/invalid-age",
"type": "ex:Person",
"schema:givenName": "Ancient",
"schema:email": "ancient@example.com",
"ex:age": 200
}
}

Error: "Age must be between 0 and 150"

Invalid Pattern​

This transaction will fail—bad email format:


{
"insert": {
"id": "ex:people/bad-email",
"type": "ex:Person",
"schema:givenName": "Test",
"schema:email": "not-an-email"
}
}

Error: "Must have a valid email address"

Valid Data Example​

{
"insert": {
"id": "ex:people/valid",
"type": "ex:Person",
"schema:givenName": "Alice",

SHACL validation ensures data quality at the database level.
