@microscopic-river-74022 Why am I getting the following error when trying to deploy a helm chart using 
garden deploy
?

Please stand by @fresh-angle-76971 as I search the knowledge base. I normally take about 15 seconds or so. :wave:
---------------------- The error message you are seeing:
Copy code
Error: INSTALLATION FAILED: file '/Users/spike/Library/Caches/helm/repository/tailscale-operator-1.86.2-1753978303-9f1ee41e298aac17db343df700f412b84d349962fbb0f680b102fa5e2c1453fd.tgz' does not appear to be a gzipped archive; got 'application/octet-stream'
indicates that Helm is trying to use a file that it expects to be a gzipped Helm chart archive (
.tgz
), but the file is either not a valid archive or is corrupted. Based on the Garden documentation, when deploying a Helm chart using Garden, you typically specify the chart using either the 
url
, 
repo
, or 
name
fields under 
spec.chart
in your module configuration. Garden then uses Helm under the hood to fetch and install the chart. If the chart cannot be fetched or is not a valid archive, Helm will fail with an error similar to what you are seeing. Possible causes based on the knowledge sources: - The chart file downloaded from the repository may be corrupted or not a valid Helm chart archive. - There may be an issue with the Helm repository itself, or with how the chart is referenced in your Garden configuration. - The 
repo
field should point to a valid Helm chart repository, and the 
name
field should specify the chart name. For example:
Copy code
yaml
  kind: Deploy
  type: helm
  name: tailscale-operator
  spec:
    chart:
      name: tailscale-operator
      repo: <https://pkgs.tailscale.com/helmcharts>
      version: "1.86.2"
This is the recommended way to reference a chart from a Helm repository in Garden. If you are using the 
url
field, ensure it points directly to a valid 
.tgz
Helm chart archive, not to a web page or an invalid file type [Installing Helm charts]().
What you can do: - Double-check your Garden module configuration to ensure you are referencing the chart correctly, as shown above. - Try clearing your local Helm cache (delete the file or the cache directory) and re-running the deployment, in case the file was corrupted during download. - Verify that the chart is available and downloadable from the specified repository and version. If the problem persists after these checks, it may be an issue with the chart repository itself or a temporary network/download problem. If you need more detailed troubleshooting steps, please provide your Garden module configuration for the Helm deploy action. > The knowledge sources do not provide more specific troubleshooting steps for this exact error, but the above guidance is based on the documented usage patterns for Helm charts in Garden [Installing Helm charts](). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@microscopic-river-74022 my deployment looks like this:
Copy code
kind: Deploy
type: helm
name: tailscale-operator
description: Install Tailscale Operator to the Kubernetes cluster 
spec:
  namespace: tailscale
  chart:
    name: tailscale-operator
    repo: https://pkgs.tailscale.com/helmcharts
m
Let me check the knowledge base for you again. One moment! :books:
---------------------- Your Garden deploy configuration for the Helm chart looks correct in terms of structure:
Copy code
yaml
kind: Deploy
type: helm
name: tailscale-operator
description: Install Tailscale Operator to the Kubernetes cluster 
spec:
  namespace: tailscale
  chart:
    name: tailscale-operator
    repo: <https://pkgs.tailscale.com/helmcharts>
However, based on the error you received, the issue is likely related to the chart version. When specifying a chart from a Helm repository, it is recommended (and often required) to also specify the 
version
field under 
chart
. Without a version, Helm may not fetch the correct chart archive, which can result in the kind of error you are seeing (“does not appear to be a gzipped archive”) [Reference: Action-types > Deploy > helm > spec.chart](). How to fix: Add the 
version
field to your 
chart
specification. For example:
Copy code
yaml
spec:
  namespace: tailscale
  chart:
    name: tailscale-operator
    repo: <https://pkgs.tailscale.com/helmcharts>
    version: "1.86.2" # Replace with the actual version you want to use
This matches the documented approach for referencing charts from a Helm repository [Installing Helm charts](). Summary: Add the 
version
field to your 
chart
block. This should resolve the error, provided the version exists in the repository and is a valid Helm chart archive. If you continue to see the error after specifying the version, try clearing your Helm cache and re-running the deployment, as a corrupted download can also cause this issue. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
