Pydantic is a data validation and settings management library for Python, leveraging Python's type annotations. It is designed to provide data parsing and validation using Python's type hints, ensuring that the data conforms to the expected types and constraints. Pydantic is widely used for validating data in web applications, APIs, and other data-driven applications.
When working with Pydantic, you might encounter the error code value_error.url.invalid_port
. This error typically arises when a URL field in your Pydantic model receives a URL with an invalid port number. The error message might look something like this:
pydantic.error_wrappers.ValidationError: 1 validation error for Model
url
invalid or missing port (type=value_error.url.invalid_port)
The error value_error.url.invalid_port
indicates that the URL provided to a Pydantic model contains a port number that is either invalid or not allowed. Ports must be integers between 1 and 65535. Any number outside this range is considered invalid. This error is raised during the validation process when Pydantic checks the URL field against the expected format and constraints.
To resolve the value_error.url.invalid_port
error, follow these steps:
Ensure that the URL you are providing is correctly formatted. Check for any typographical errors or misplaced characters. A valid URL should look like this:
http://example.com:8080/path
Verify that the port number in the URL is within the valid range of 1 to 65535. If the port number is outside this range, adjust it to a valid number. For example, if your URL is:
http://example.com:70000/path
Change it to a valid port number:
http://example.com:8080/path
Ensure that your Pydantic model is correctly defined to accept URLs. Here is an example of how you might define a model with a URL field:
from pydantic import BaseModel, HttpUrl
class MyModel(BaseModel):
url: HttpUrl

By following these steps, you should be able to resolve the value_error.url.invalid_port
error and ensure that your URL fields are correctly validated in your Pydantic models.
