Error: rpc error: code = Unavailable desc = transport is closing

[andrewnazarov]

I'm moving forward from the previous version to the most recent and the latest fails for all our environment with

Error: rpc error: code = Unavailable desc = transport is closing

during terraform plan stage. There are no changes in any helmfile state except for one. And for that specific environment, the error is the same. Retry didn't help.

helmfile version: v0.109.0

Turning debug on I've got the following:

@andrewnazarov Thanks! I've successfully reproduced this and it's fixed in v0.3.4.

// I've recently changed the default path from "helmfile.yaml" to "", and this bug was introduced due to some deficiency in the migration logic in the provider to rewrite the state for default values change.

[andrewnazarov]

I'm sorry to say that, but Error: Provider produced inconsistent final plan strikes back (https://github.com/mumoshu/terraform-provider-helmfile/issues/22)

For environments that have no helmfile state changes terraform apply works and I can confirm it's faster than the intermediate working version was. For environments that have helmfile state changes terraform apply fails with the aforementioned Error: Provider produced inconsistent final plan.
