I retrieved the latest version of the ask-cli (2.2.0) and I was trying to give a try on a fresh example. I chose the ask new command with the Hello World template, with the CloudFormation option. Then, I do nothing more than ask deploy which indeed deploys everything to AWS (I can see the Lambda) and Alexa (I can see the skill). When I run the ask dialog --locale en-US command, and then demand to open hello world, and error is prompted.

See the full log below.

Expected Behavior

Well, that it works like in the tutorial.

Current Behavior

The lambda (runtime : Node.js 12.x, but I tried 10.x with same result) seems to direct-crash at startup, and it's because of this error (which I see in the CloudWatch). Aparently, some data are not found from ask-sdk-runtime

{
  "errorType": "Runtime.ImportModuleError",
  "errorMessage": "Error: Cannot find module './dispatcher/error/mapper/GenericErrorMapper'\nRequire stack:\n- /var/task/node_modules/ask-sdk-runtime/dist/index.js\n- /var/task/node_modules/ask-sdk-core/dist/attributes/AttributesManagerFactory.js\n- /var/task/node_modules/ask-sdk-core/dist/index.js\n- /var/task/index.js\n- /var/runtime/UserFunction.js\n- /var/runtime/index.js",
  "trace": [

    "    at _loadUserApp (/var/runtime/UserFunction.js:100:13)",
    "    at Object.module.exports.load (/var/runtime/UserFunction.js:140:17)",
    "    at Object.<anonymous> (/var/runtime/index.js:43:30)",
    "    at Module._compile (internal/modules/cjs/loader.js:1158:30)",
    "    at Object.Module._extensions..js (internal/modules/cjs/loader.js:1178:10)",
    "    at Module.load (internal/modules/cjs/loader.js:1002:32)",
    "    at Function.Module._load (internal/modules/cjs/loader.js:901:14)",
    "    at Function.executeUserEntryPoint [as runMain] (internal/modules/run_main.js:74:12)",
    "    at internal/main/run_main_module.js:18:47"
  ]
}

Also, I retrived the .zip file on the S3 bucket declared in the CloudFormation, that is used for the Lambda : it contains a full node_module folder, including the file in node_modules\ask-sdk-runtime\dist\dispatcher\error\mapper ...

Possible Solution

No idea...
