- postmortem Apr 30, 2026, 06:03 PM UTC
**Update #1** On April 28 at approximately 15:00 UTC and again on April 29 at approximately 15:22 UTC, a load spike affected our internal task queue, which slowed down the mechanism Scalr uses to transition runs between pipeline stages. In some cases, the transition task failed before it could complete, leaving runs stuck in a waiting state with no automatic recovery path. Both times, the queues cleared on their own while our engineering team investigated. We have already shipped an improvement \(released April 30\) that makes this transition task significantly more resilient to lock contention, greatly reducing the likelihood of runs getting stuck. We are continuing to investigate the underlying cause of the queue spikes and will share further updates as the investigation progresses.

Runs Are Not Using the Account Level Default Agent Pool
Affected: Scalr Platform
Timeline · 3 updates
- investigating Oct 07, 2025, 08:42 PM UTC
Runs are not using agents if the agent is set as the default for the account. A workaround, for now, is to set the agent pool in the workspace settings explicitly. A fix is in progress to ensure that the account-level defaults are used as expected.

Runs failing with "flag provided but not defined: -var-file"
Timeline · 2 updates
- resolved May 07, 2025, 01:21 PM UTC
We're currently working on a fix for runs that are failing with: │ Error: Failed to parse command-line flags │ │ flag provided but not defined: -var-file
- postmortem May 07, 2025, 01:22 PM UTC
**RCA** A fix was released to ensure `.tfvars` files are properly loaded during the `init` phase with `for-each` feature, that was introduced in the OpenTofu [1.9.0](https://opentofu.org/blog/opentofu-1-9-0/) version. Technical details: * To fix the issue we added processing of the `.tfvars` on `init`, `validate, `and `fmt` phases for runs with the flag `-var-file.` * But consuming the `.tfvars` file using the `-var` and `-var-file` options was introduced in OpenTofu [1.8.0](https://opentofu.org/docs/v1.8/intro/whats-new/), and exception handling was missed for any versions less than 1.8.0. * Because of this, all runs with `.tfvars` files in the VCS-driven workspaces with OpenTofu < 1.8.0 and all Terraform versions supported by Scalr were affected.
