Cases when Salesforce Apex does not work

1. When the code exceeds the governor limits: Salesforce Apex has certain limits on the resources used by a single transaction or request. These limits include CPU time, heap size, database queries, and more. If the code surpasses these limits, it can result in exceptions, failures, or even termination of the transaction.
2. When there are issues with test coverage: Salesforce requires a minimum percentage of code coverage by unit tests to deploy Apex code to production. If the code lacks sufficient test coverage, it cannot be deployed. Therefore, it is crucial to ensure that all classes, triggers, and methods have appropriate test classes that cover a significant portion of the code.
3. When there are security restrictions: Salesforce enforces various security restrictions to protect sensitive data and maintain the integrity of the platform. If the Apex code tries to access or modify restricted data, it will be blocked. Additionally, if the code violates security policies, such as sharing rules or field-level security, it may result in errors or unexpected behavior.
4. When there are validation rules or triggers in conflict: Salesforce allows the creation of validation rules and triggers to enforce business logic and data integrity. However, conflicts can arise when the code and the data validation rules or triggers have conflicting requirements. This can lead to unexpected errors or incorrect data modifications.
5. When there are platform version dependencies: Salesforce periodically releases new platform versions that introduce enhancements and changes to the Apex language. If the code relies on deprecated features or uses older syntax incompatible with the current platform version, it may break or produce unexpected results. It is essential to keep the code up-to-date with the latest platform version to avoid compatibility issues.
