Error 412 "Precondition Failed" occurs when a client sends a request that contains preconditions (such as an If-Match or If-None-Match condition) to check the integrity or version of a resource, and those conditions are not met on the server side. This error indicates that the preconditions specified by the client do not match the current state of the resource on the server.
The reasons for the 412 "Precondition Failed" error may be the following:
Precondition Mismatch: The preconditions specified in the request (for example, If-Match or If-None-Match) do not match the current state of the resource on the server.

Server does not support prerequisites: Some servers may not support certain prerequisites, which may cause an error.
Invalid Precondition Values: If the precondition values are specified incorrectly, it can also cause an error.
To fix the 412 "Precondition Failed" error, you can take the following steps:
Check preconditions: Make sure that the preconditions (such as If-Match or If-None-Match) are specified correctly in the request and match the current state of the resource.
Check the expiration date of the terms and conditions: If the prerequisites are valid for a certain period of time, make sure they have not expired.
Use supported conditions: Make sure the server supports the specified prerequisites. Check the documentation for supported conditions.
Check the API documentation: If the error is related to API usage, refer to the documentation for information on how to properly use prerequisites.

Change the prerequisites: If the prerequisites are incorrect, change them to the correct values.
