Same issue here, builds are still failing

Can you please link to a specific build that has failed.

Sure, these are the logs from the latest failed build: https://railway.com/project/7089e588-1023-47ae-855e-81720df14929/logs?environmentId=1a126d2c-a7a6-48e8-84f2-5d8b946591dc&filter=%40snapshot%3Af16f34f8-c8ee-45fe-a28e-02eaca1baa94+OR+%40replica%3Af16f34f8-c8ee-45fe-a28e-02eaca1baa94&context=2025-08-01T14%3A11%3A03.438027157Z&start=1754057453891

Let me know if you need anything else or I should link in another format

Please link to a deployment instead of using the logs tab.

Maybe this is a better way of sharing? https://railway.com/project/7089e588-1023-47ae-855e-81720df14929/service/a136ef14-d375-4a82-86e1-a222414ff1d5?context=2025-08-01T14%3A11%3A03.438027157Z&environmentId=1a126d2c-a7a6-48e8-84f2-5d8b946591dc&id=6619a7d0-cabb-4bf9-bfc5-714d320080df&forceViewAll=true#build

In any case I think these are the relevant lines:

@brody Is there a way to force railpack to use a an older builder image? This would be a good workaround when something goes wrong with the latest update. I haven't found anything in the config and it seems to pull the latest version by default.

The issue isn't a new Railpack version or anything like that, the issue is upstream from Railpack.

Thank you. I have staged a variable change for you. Please apply it at your earliest convenience and let me know if that solves the build issue.

Thank you, this seem to be working I added it to another deployment, and it also worked there.

We have a production environment as well, will deploy that later today too, and if needed I'll add the ENV variable there as well if needed.

Is there anything else I should do?

Thank you for letting me know it has worked. If you run into the same issue on other services, you should indeed use the same variable.

But beyond that, no further action is needed on your part, since we will be looking into applying this patch automatically from within Railpack.
