Builder

Builder is a mechanism that is used to build a function when creating its new version. It loads the necessary dependencies and, if a compiled programming language is used, compiles the source files into an executable file.

Logging

The builder's output data is written to a file and returned to the user both if the version is created successfully and if it's not. You can find a link to this file in the operations section.

If the builder reports a project build error, the runtime environment automatically captures the error, writes detailed information about the error type, text, and location to a log file and returns a link to this file in the response. As a result, the function version creation fails.
