From inspecting the source, it looks like it's failing to read the entrypoint from one of my ~30 functions. How do I know which one? How do I know why?

Have you tried to add a console.log to the resolveFilePathsFunction function?

Actually, I have a better idea:

module.exports = class {
     const allFiles = await Map(
       this.serverless.service.getAllFunctions(),
       (fnName) => {
-        return this.resolveFilePathsFunction(fnName);
+        return this.resolveFilePathsFunction(fnName).catch((error) => {
+          console.error(error, { fnName });
+          return [];
+        });
       },
     );
