The error indicates that the connector sidecar is trying to initialize a GCS storage client but cannot find the credentials file at

/secrets/gcs-log-creds/gcp.json

inside the MSSQL source pod: >

Caused by: java.nio.file.NoSuchFileException: /secrets/gcs-log-creds/gcp.json

From the issues and docs, this happens when: 1. The GCS credentials secret is not mounted into job/connector pods, or 2. The Helm values for the container orchestrator secret name/mount path don’t match where the file actually is, or 3. The GCS storage configuration keys differ between Helm v1 and v2. Relevant points from the knowledge sources: - Jobs/connector pods expect the GCP JSON at

/secrets/gcs-log-creds/gcp.json

and will fail if it’s missing. [[GCP JSON not mounted](https://github.com/airbytehq/airbyte/issues/65153); [Using container orchestrator](https://discuss.airbyte.io/t/2207)] - For Helm v2, you must explicitly configure the container orchestrator secret and mount path so that the GCP JSON is available in job pods: [[GCP JSON not mounted](https://github.com/airbytehq/airbyte/issues/65153)]

yaml   global:     workloads:       containerOrchestrator:         secretName: "airbyte-gcs-logs-creds"         secretMountPath: "/secrets/gcs-log-creds"

(Replace

"airbyte"

in the secret name with your Helm release name.) [[GCP JSON not mounted](https://github.com/airbytehq/airbyte/issues/65153)] - When using GCS storage with Helm v2, some keys changed compared to v1 (case-sensitive

type

, and

credentialsJsonSecretKey

instead of

credentialsPath

). [[Container launcher not using creds](https://github.com/airbytehq/airbyte/issues/68177); [global.storage.secretName issue](https://github.com/airbytehq/airbyte/issues/48842)] So the issue is: the GCS credentials file is not present at

/secrets/gcs-log-creds/gcp.json

in the MSSQL source pod because the secret is not mounted (or not mounted at that path) for workload/connector pods. To fix, based on the sources: 1. Ensure you have a Kubernetes secret containing

gcp.json

(e.g.

airbyte-gcs-logs-creds

or

<release-name>-gcs-logs-creds

) with the key

gcp.json

. [[State & logging storage](https://docs.airbyte.com/platform/deploying-airbyte/integrations/storage#values)] 2. In your Helm values, set:

yaml    global:      workloads:        containerOrchestrator:          secretName: "<your-release-name>-gcs-logs-creds"          secretMountPath: "/secrets/gcs-log-creds"

so that

/secrets/gcs-log-creds/gcp.json

exists in job/connector pods. [[GCP JSON not mounted](https://github.com/airbytehq/airbyte/issues/65153)] 3. If you’re on Helm v2 and using GCS for storage, also verify the

global.storage

section uses the correct keys (

type: "GCS"

or

"gcs"

depending on chart, and

credentialsJsonSecretKey

if applicable) as described in the issues. [[Container launcher not using creds](https://github.com/airbytehq/airbyte/issues/68177); [global.storage.secretName issue](https://github.com/airbytehq/airbyte/issues/48842)] Once the secret is correctly mounted at

/secrets/gcs-log-creds

with a

gcp.json

file, the

WorkloadOutputWriter

/

GcsStorageClient

should initialize and the MSSQL source pod should start successfully.
