Error: Cannot find module 'ts-tiny-invariant'

I just upgraded to apollo-server-core: 3.0.1. When I deploy my code to AWS Lambda with ESBuild I get the following error

Error: Cannot find module 'ts-tiny-invariant'
Require stack:
- /var/task/index.js
- /var/runtime/UserFunction.js
- /var/runtime/index.js

I am creating a new server with apollo-server-express

I’m not 100% sure but this might be caused by ts-is-defined being compiled with Typescript 3.x https://github.com/iyegoroff/ts-is-defined/blob/master/package.json#L40

The compiled code after ESBuild is the following for ts-is-defined

// node_modules/ts-is-defined/dist/umd/index.js
var require_umd2 = __commonJS({
  "node_modules/ts-is-defined/dist/umd/index.js"(exports2, module2) {
    var __importDefault = exports2 && exports2.__importDefault || function(mod) {
      return mod && mod.__esModule ? mod : { "default": mod };
    };
    (function(factory) {
      if (typeof module2 === "object" && typeof module2.exports === "object") {
        var v = factory(require, exports2);
        if (v !== void 0)
          module2.exports = v;
      } else if (typeof define === "function" && define.amd) {
        define(["require", "exports", "ts-tiny-invariant"], factory);
      }
    })(function(require2, exports3) {
      "use strict";
      Object.defineProperty(exports3, "__esModule", { value: true });
      exports3.assertIsDefined = exports3.isDefined = void 0;
      var ts_tiny_invariant_1 = __importDefault(require2("ts-tiny-invariant"));
      function isDefined(value) {
        return value !== void 0 && value !== null;
      }
      exports3.isDefined = isDefined;
      function assertIsDefined(value, message) {
        ts_tiny_invariant_1.default(isDefined(value), message);
      }
      exports3.assertIsDefined = assertIsDefined;
    });
  }
});

And here is ts-tiny-invariant defined in the same file

// node_modules/ts-tiny-invariant/dist/umd/index.js
var require_umd = __commonJS({
  "node_modules/ts-tiny-invariant/dist/umd/index.js"(exports2, module2) {
    (function(factory) {
      if (typeof module2 === "object" && typeof module2.exports === "object") {
        var v = factory(require, exports2);
        if (v !== void 0)
          module2.exports = v;
      } else if (typeof define === "function" && define.amd) {
        define(["require", "exports"], factory);
      }
    })(function(require2, exports3) {
      "use strict";
      Object.defineProperty(exports3, "__esModule", { value: true });
      var isProduction = process.env.NODE_ENV === "production";
      var prefix = "Invariant failed";
      function invariant(condition, message) {
        if (condition) {
          return;
        }
        throw new Error(isProduction ? prefix : prefix + ": " + (message || ""));
      }
      exports3.default = invariant;
    });
  }
});

I removed the ts-is-defined dependency from @graphql-tools/mock and the most recent patch of @graphql-tools/mock has the fix applied. apollo-server pulled the patch in #5552 so it should be fixed in the next release.

I manually patched my lockfile and confirmed that the fix works in a lambda environment.

Hey @glasser we are having the same issue by using “Serverless-stack: https://serverless-stack.com”, it uses esbuild under the hood.

The Apollo Server runs fine locally but on AWS Lambda the built version crashes with this error too:

Error: Cannot find module 'ts-tiny-invariant'

Is it possible to reopen this issue?
