Panic Output

Steps to Reproduce

1. terraform apply

Expected Behavior

Changes have been applied successfully.

Actual Behavior

1. error appears

Error: failed to download "https://${token}@raw.githubusercontent.com/${org}/helm-repo/tmp/grafana-5.5.7.tgz" (hint: running `helm repo update` may help)


2021-01-13T12:26:05.297+0200 [WARN]  plugin.stdio: received EOF, stopping recv loop: err="rpc error: code = Unavailable desc = transport is closing"

2. after re-run of terraform apply the update plan is up to date(no changes detected), seems like it updates the state during the failed run

Important Factoids

• it was working before 2.0.1
• dynamically reproduced in majority of cases
• we have CD with the similar steps to the local ones with terraform initialization and this error is not reproduced there

References

• Always do helm repo update #630
• When the release fails for any reason do not update the state #472
• verify flag throws Error: failed to download (hint: running helm repo update may help)  #554
• Possibility to point directly to a chart on github or similar #465

tested on provider 2.0.0, same error

[eprokofev]

helm provider 1.3.2 - same behaviour

[eprokofev]

added variable HELM_DEBUG=1 and did apply one more time. Got more specific error
Error: no cached repo found. (try 'helm repo update'): open /Users/****/Library/Caches/helm/repository/incubator-index.yaml: no such file or directory
on helm.tf line 1, in resource "helm_release" "alb_ingress_controller": 1: resource "helm_release" "alb_ingress_controller" {

After that I've tried to runhelm repo update manually and got an error: ...Unable to get an update from the "incubator" chart repository (https://kubernetes-charts-incubator.storage.googleapis.com): failed to fetch https://kubernetes-charts-incubator.storage.googleapis.com/index.yaml : 403 Forbidden

So I removed that incubator repo from my helm config.
After that I've applied helm chart with terraform successfully.
