400 Bad Request

Error Code: 400​

This error primarily occurs when there are validation errors in the JSON schema.

Error Message​

  • "One or more validations failed trying to process your request."
  • "PrismaClientKnownRequestError: <Error Code>"
  • "Web Media Profile must have credentialSubject.id"
  • "Profile Annotation must have credentialSubject.id"
  • "<Error message during Site Profile verification>"

Causes​

  • The input JSON may not meet the expected schema (required fields, types, and format).
  • A PrismaClientKnownRequestError (other than P2025) may have occurred. (See the Prisma Error Reference for details.)
  • The credentialSubject.id may not have been included when registering or updating the Web Media Profile or Profile Annotation.
  • Site Profile verification may have failed when registering or updating the Site Profile. (See the Site Profile for details.)

Examples​

  • The following is an example where the required field issuer is not included.
{
  "@context": [
    "https://www.w3.org/ns/credentials/v2",
    "https://originator-profile.org/ns/credentials/v1",
    "https://originator-profile.org/ns/cip/v1",

    },
    "description": "An example web page for content attestation",
    "author": ["John Doe"],

  },
  "allowedUrl": ["https://example.com/*"],

    {
      "type": "TextTargetIntegrity",
      "cssSelector": "#main",
      "content": "data:text/html,<div id=\"main\">Hello, world!</div>"
    }
  ]
}

Output:

{"statusCode":400,"error":"Bad Request","message":"One or more validations failed trying to process your request.","failedValidations":{"body":{"issuer":"must be present"}}}

Resolution​

  • Check the required fields, types, and format of the input JSON, or the error details in the response message.
  • If a PrismaClientKnownRequestError occurs, refer to the Prisma error reference.
  • Ensure that credentialSubject.id is included in the Web Media Profile and Profile Annotation.
  • Modify the input content so that the Site Profile validation passes.
