Abstract: Computer-interpreted scripts (“scripts”) execute instructions, such as to serve as a client in a client-server application. However, scripts may contain hardcoded temporary values that expire and, as a result, cause replaying the script to fail. By identifying the problem (e.g., an error message), gathering data available, and generating a prompt to a large language model (LLM), a resolution to the error may be provided and results in a modified script. Optionally, the resolution is evaluated, such as to correct any hallucinations of the LLM. A replay engine then replays the modified script and, if successful, the error is resolved. In one embodiment, the error is a hardcoded value that is no longer valid. Such a value is detected and replaced with a variable having a value determined form preceding operations of the script.
