`deno cache` failing with error sending request for url: dispatch task is gone: runtime dropped the dispatch task

[ishmam-mahmud]

This does not happen locally. It seems to only be affecting our Dockerfile when it runs on our render.com deployment.

Here's a section of the Dockerfile that's causing the issue

FROM denoland/deno:1.31.1

ARG SERVICE_NAME

EXPOSE 8000

WORKDIR /app

USER deno

# Copy dependencies files
ADD --chown=deno:deno ./import_map.json .
ADD --chown=deno:deno ./deps.ts .
# Cache dependencies
RUN deno cache --import-map=import_map.json deps.ts

# Copy shared dir
ADD --chown=deno:deno ./shared ./shared

# Copy service
ADD --chown=deno:deno ./services/${SERVICE_NAME} ./services/${SERVICE_NAME}

WORKDIR /app/services/${SERVICE_NAME}

RUN deno cache ./main.ts

CMD ["run", "--allow-net", "--allow-read", "--allow-env", "--allow-write", "--allow-sys", "main.ts"]

This is a monorepo structure, where each service is in a services folder, and the shared folder contains custom libraries used by multiple services.

The error message from the docker CLI itself:

29.63 Download https://registry.npmjs.org/follow-redirects/-/follow-redirects-1.15.4.tgz
32.64 error: error sending request for url (https://deno.land/std@0.175.0/async/tee.ts): dispatch task is gone: runtime dropped the dispatch task

The url/specific dependency that causes the failure is different everytime, but it's usually a deno.land/std package or a deno.land/x package.

The error is reproducible locally if I run docker build . It just doesn't happen if I run deno cache myself

Hi @ishmam-mahmud. Have you seen this issue very recently, like in the past two hours or so? We applied a small change to our backend a few hours ago. I wonder if it's related.

Hi @ishmam-mahmud. Have you seen this issue very recently, like in the past two hours or so? We applied a small change to our backend a few hours ago. I wonder if it's related.

We saw this issue the first time around 2024-01-09T17:04:27.000+08:00, or 2024-01-09T09:04:27.000Z in UTC

[magurotuna]

Thanks for the info. The time we applied a change was around 9:30 AM UTC, so I suppose this backend change has nothing to do with this issue. But we'll look into it a bit more.

[magurotuna]

Sorry I mistakenly closed it. Reopening now.

@ishmam-mahmud Could you try again your workflow? We've done a small change yet again to deno.land/x backend, although we're not sure if this fixes your issue.

[ishmam-mahmud]

We started getting a different error at first: 500 Internal Server Errors, but after a few retries we managed to deploy all our services successfully. Everything's green now.

For reference, there is also a widespread GitHub outage going on today: https://www.githubstatus.com/incidents/pxg3dz4yg7lp

[magurotuna]

@ishmam-mahmud Thanks for confirmation. Glad that your issue has been solved. I think all related issues have also been resolved by the change we made to the backend, so I'll close this issue now. Feel free to reopen if it still occurs.
