I’m running a GitHub action to download images from an api every hour, I used the nasa image example as the template. However sometimes the run fails with this error, what could be the issue?

here’s the failed run:
https://github.com/weirdyang/causeway-image/actions/runs/1737018565
Here’s my post process script

Hi there! Thanks for reporting this. Could you try upgrading your version of the postprocessing library to 0.0.13

So here: https://github.com/weirdyang/causeway-image/blob/main/post-process.js#L4

import { readImageFromURL, readJSON, writeImage } from 'https://deno.land/x/flat@0.0.13/mod.ts';

And let us know if the error still happens for you?

[weirdyang]

Still failed

Happening to me as well! Also on 0.0.13

I did some digging here - looks like these errors are very intermittent and fail while downloading different modules required for the xlsx import from jspm.

For example, this Action fails on https://jspm.dev/npm:@jspm/core@2/nodelibs/process
https://github.com/weirdyang/causeway-image/runs/4997125928?check_suite_focus=true

but this Action fails on https://jspm.dev/npm:@jspm/core@2/nodelibs/buffer
https://github.com/weirdyang/causeway-image/runs/4998890994?check_suite_focus=true

One other thing I noticed is that the errors appear to start ~Jan 10th, looking through the history on your repo, @dalanmiller. Looks like there was an xlsx release around the same time:

I pinned the xlsx import to v0.17.4
https://deno.land/x/flat@0.0.14/src/xlsx.ts#L1

I'm not positive that this will fix the error, but it might! Try bumping your flat import to 0.0.14, and we can revisit if the errors are still showing up.

[dalanmiller]

Thanks for investigating @Wattenberger - I bumped to 0.0.14 and I'm still getting the same issue it seems.

Has anything changed to the Deno runtime behind the scenes?

Edit:

But oddly, it's intermittent, this recent run succeeded:

[weirdyang]

Thanks, will try and report back. Fwiw I noticed the examples are also failing intermittently https://github.com/githubocto/flat-demo-bitcoin-price/actions/runs/1778265780

Thanks, will try and report back. Fwiw I noticed the examples are also failing intermittently https://github.com/githubocto/flat-demo-bitcoin-price/actions/runs/1778265780

This might have been because we hadn't updated the flat-demo-bitcoin-price to use 0.0.14 but we just did to see what happens.

[irealva]

Following-up @dalanmiller it doesn't seem like your action has failed in a while, is that correct ?https://github.com/dalanmiller/electricity/actions?

[irealva]

Also will leave a comment to follow this issue which Amelia found: SheetJS/sheetjs#2217

[weirdyang]

Just bumped to 14, fwiw didn’t get any errors the past few days with 13

[andmos]

I had the some error all of a sudden, looks like a bump to 0.0.14 did the trick.

[Wattenberger]

Thanks for the reports y'all! Looks like runs have stopped intermittently failing 🙌 Please let us know if it starts happening again, and hopefully we can stop using jsnpm for Sheetjs soon
