#10136
invalid_argument_error
Invalid response received: Ensure that multiturn requests alternate between user and model for proper processing.
This error has been identified and solved.
Reason
The 400 status error you are encountering in the Google API, specifically with the message "Please ensure that multiturn requests alternate between user and model.", indicates that the structure of your requests is not adhering to the expected pattern. This error suggests that your multiturn requests (those involving multiple interactions or turns) are not alternating correctly between user inputs and model responses.
In other words, the API expects a sequence where each turn is either a user input or a model response, and your current requests are not following this alternating pattern, leading to an INVALID_ARGUMENT error.
Solution
To fix the 400 INVALID_ARGUMENT error with the message "Please ensure that multiturn requests alternate between user and model.", you need to ensure that your multiturn requests follow the correct sequence of alternating between user and model roles.
Here are the key steps to correct this issue:
Adjust the message history to alternate strictly between 'user' and 'model' roles.
Ensure the last message in the history is from the 'model' if the next turn is expected from the 'user', and vice versa.
Check for any consecutive messages with the same role and restructure them accordingly.
By making these adjustments, you can ensure your requests comply with the API's expectations and resolve the error.
