What is HTTP Request Error 422 Invalid Parameters in DeepSeek API?
The DeepSeek API Error 422 occurs when a request sent to the DeepSeek API contains invalid or unsupported parameters. This may be due to incorrect API configurations, network issues, or server errors. The error prevents successful communication with the AI model, making it crucial to identify and correct any invalid request parameters.
How to Fix DeepSeek API Error 422 - Invalid Parameters
Before making changes to your API request, check if the issue is due to server downtime or maintenance. Visit the [DeepSeek Service Status Page] to verify whether the API is operational. If there’s an outage, wait until the service is restored and try again. Outages are quite common with DeepSeek so there's a good chance that this is the problem you are getting, so jus wait and try again later.
Make sure you are using Proper JSON Formatting
DeepSeek R1 communicates using JSON-formatted requests. If your request is improperly formatted, the API may not understand it, leading to an error.
- Use valid JSON syntax, including proper brackets ({}, []) and quotation marks ("").
- Validate your JSON before sending requests using online tools such as [JSON Validator].
- Ensure no missing commas or incorrect nesting structures are present.
Review and Validate Request Parameters
DeepSeek R1 does not support all parameters that other AI models might accept. Ensure that your API request does not include unsupported parameters such as:
- temperature
- top_p
- presence_penalty
- frequency_penalty
- logprobs
- top_logprobs
If your request contains any of these, remove or modify them based on the API’s accepted parameters.
Use a Valid API Key
Invalid or unauthorized API keys can cause request validation failures. To fix this:
- Ensure you’re using the correct API key.
- If your API key is expired or revoked, generate a new one from your DeepSeek account.
- Free-tier API keys may have limitations, so check whether your key supports the requested parameters.
