[bug]: `env.doc_upload_size_limit` does not correctly override `FILE_SIZE_LIMIT`

Is there an existing issue for this?

• I have searched the existing issues

Current behavior

When setting doc_upload_size_limit through values.yaml, the document upload size limit does not appear to be applied correctly.

Example:

env:
  doc_upload_size_limit: "104857600"

After rendering the Helm chart, the generated Secret/ConfigMap contains:

stringData:
  FILE_SIZE_LIMIT: "5242880"

However, the effective upload size limit does not change as expected.

The limit only worked correctly after using file_size_limit instead:

env:
  file_size_limit: "104857600"

So doc_upload_size_limit appears to either not map correctly to the effective FILE_SIZE_LIMIT, or it is being ignored in favor of file_size_limit.

Expected behavior

Setting this in values.yaml:

env:
  doc_upload_size_limit: "104857600"

should correctly configure the effective file upload size limit.

The rendered value should match the configured value and be applied by the application:

stringData:
  FILE_SIZE_LIMIT: "104857600"

Actual behavior

Using:

env:
  doc_upload_size_limit: "104857600"

does not correctly override the effective upload size limit.

The limit only works when using:

env:
  file_size_limit: "104857600"

Steps to reproduce

1. Deploy Plane using the Helm chart.

2. Set a custom document upload size limit in values.yaml:

env:
  doc_upload_size_limit: "104857600"

3. Apply the Helm release:

helm upgrade --install plane-app <chart-name> \
  --namespace plane \
  -f values.yaml

4. Check the rendered Secret/ConfigMap:

helm get manifest plane-app -n plane | grep -A 5 FILE_SIZE_LIMIT

5. Confirm that FILE_SIZE_LIMIT is not correctly replaced with the configured doc_upload_size_limit value.

6. Test uploading a file larger than the default limit.

7. Notice that the configured doc_upload_size_limit is not applied.

8. Change the configuration to use file_size_limit instead:

env:
  file_size_limit: "104857600"

9. Apply the Helm release again:

helm upgrade --install plane-app <chart-name> \
  --namespace plane \
  -f values.yaml

10. Test the upload again and confirm that the custom size limit now works.

Workaround

Use file_size_limit instead of doc_upload_size_limit:

env:
  file_size_limit: "104857600"

Suggested fix

The Helm value env.doc_upload_size_limit should correctly map to the effective FILE_SIZE_LIMIT value, or the documentation should be updated to indicate that env.file_size_limit is the correct setting to use.

For example, this configuration:

env:
  doc_upload_size_limit: "104857600"

should render and apply:

stringData:
  FILE_SIZE_LIMIT: "104857600"
