Incorrect request format, missing parameters, or invalid model configurations often cause the "Request contains invalid argument" error on Google Cloud AI Platform.
Here is the code snippet you can refer to:

In the above code, we are using the following key approaches:
- Validate Request Structure: Ensure correct payload format and required fields.
- Check Model Endpoint: Confirm the endpoint URL is properly set up.
- Inspect Data Types: Match input types with model expectations.
- Monitor API Quotas: Ensure usage is within rate limits.
- Use Logging: Enable logging to identify invalid request details.
Hence, verifying request format, data types, and API configurations helps resolve the "Request contains invalid argument" error on Google Cloud AI Platform.
