cloud-slack-bot's Issues

Error occurred during docker run container

Hi, I have some error on this project.
(When i study https://google.qwiklabs.com/focuses/635, Testing a Docker image locally)
I guess this error can occur botkit node version support.

google**_student@cloudshell:~/cloud-slack-bot/step-4-update (qwiklabs-gcp-***)$ kubectl logs slack-codelab-7f5f547fcf-rdg7j
/src/node_modules/botkit/lib/SlackBot.js:235
            let timestamp = req.header('X-Slack-Request-Timestamp');
            ^^^

    at Object.Module._extensions..js (module.js:404:10)

When I used it like this Dockerfile, no error occurred.

FROM node:7
COPY package.json /src/package.json
WORKDIR /src
RUN npm install
COPY kittenbot.js /src
CMD ["node", "/src/kittenbot.js"]

I'm not sure this change can be solutions.
please check!

Thanks.

App does not start and fails with message "Cannot find module 'request'"

Issue

I'm currently updating the parent codelab to deploy cloud-slack-bot to Cloud Run (incl. removing usage of Container Registry):

• ✔️ Cloud Build does build/deploy the container (Dockerfile ok)
• ❌ The container fails to start with this error message: Cannot find module 'request'
• ℹ️ This has been reproduced with the source under cloud-slack-bot/start
• ❔ cloud-slack-bot/extra-credit has probably the same issue

Reproduction steps

git clone https://github.com/googlecodelabs/cloud-slack-bot.git
cd cloud-slack-bot/start
gcloud run deploy kittenbot \
  --source . \
  --platform managed \
  --region $REGION \
  --set-env-vars PROJECT_ID=$PROJECT_ID \
  --allow-unauthenticated
