Invalid Input¶

Type URI: https://arcp.0x001.tech/docs/problems/invalid-input
HTTP Status: 400 Bad Request
Title: Invalid Input Data

Description¶

This problem occurs when the format or structure of input data is incorrect, but not necessarily a validation rule violation.

Example Response¶

{
  "type": "https://arcp.0x001.tech/docs/problems/invalid-input",
  "title": "Invalid Input Data",
  "status": 400,

  "request_id": "req_input123",
  "input_error": "Expecting ',' delimiter: line 3 column 5 (char 42)"
}

Common Issues¶

1. Malformed JSON¶

# Invalid JSON (missing quotes)
curl -X POST "http://localhost:8001/agents/register" \
  -H "Content-Type: application/json" \
  -d '{agent_id: "test"}'  # Wrong - keys need quotes

# Valid JSON
curl -X POST "http://localhost:8001/agents/register" \
  -H "Content-Type: application/json" \
  -d '{"agent_id": "test"}'  # Correct

2. Wrong Data Types¶

# Wrong data type (string instead of array)
curl -X POST "http://localhost:8001/agents/register" \
  -H "Content-Type: application/json" \
  -d '{"capabilities": "processing"}'  # Wrong

# Correct data type
curl -X POST "http://localhost:8001/agents/register" \
  -H "Content-Type: application/json" \
  -d '{"capabilities": ["processing"]}'  # Correct

Resolution Steps¶

1. Validate JSON Format¶

Use a JSON validator to check your request data structure.

2. Check Data Types¶

Ensure all fields match expected types (string, array, object, etc.).

3. Review API Documentation¶

Verify the expected request format for the endpoint.
