hey everyone, we are running Infracost in a GitHub workflow, and we are seeing an error which doesn’t tell us much: > Error: template: markdown-html.tmpl89111: executing “markdown-html.tmpl” at .PastBreakdown.TotalMonthlyCost: nil pointer evaluating *output.Breakdown.TotalMonthlyCost followed by: > 2024-02-22T143920Z ERR request failed error Post “https://pricing.api.infracost.io/event”: context deadline exceeded (Client.Timeout exceeded while awaiting headers) method POST url https://pricing.api.infracost.io/event library=retryablehttp Can anyone share their thoughts about what we’re doing wrong? Note: other three jobs in the same pipeline complete successfully and they are using Infracost as well.

Thanks @billowy-electrician-57321, I’m wondering if it helps if you pass in
--terraform-var-file
to the first breakdown command?

for the baseline? I can try that 🙂 This is shared action btw, not sure if that makes any difference

Yeah for the baseline.

I’ll try and get back to you, thank you very much for quick response 🙂

no problem. Let me know and if that doesn’t work in I can dive into it more.

no change unfortunately, we also bumped the Infracost action version to 2.1.0

Okay, so looking into it looks like somehow the
infracost-PR-diff.json
must be missing a past breakdown for a project. Are you able to DM me that file and the
infracost-baseline.json
file that’s causing this?

hey Alistair, sorry for the delay. Could it be it errors out since we had no prior cost breakdown for that particular set of resources? They are actually being created for the first time, and since they didn’t exist infracost breakdown was never created before 🤔
yup, after merging the PR and creating a new one the error went away 🙂 Thank you for your help 🙂

Thanks @billowy-electrician-57321, I haven’t been able to reproduce it yet but found a similar bug that might be related, so will get that out in the next release.
