Hi all, I need a support or suggestion from everyone,

I 'm using library google-cloud-notebooks==1.7.0. The under is my example code to create and health check a execution.

from google.cloud.notebooks_v1 import CreateExecutionRequest, GetExecutionRequest
from google.cloud.notebooks_v1.services.notebook_service import NotebookServiceClient

# Create client
client = NotebookServiceClient(credentials=credential)
# Create request template
request_create_execution = CreateExecutionRequest(
                               parent=PARENT,
                               execution_id=f"trigger_vertex_notebook_{uuid.uuid4().hex}",
                               execution=EXECUTION_TEMPLATE,
)
# Create a execution
operation = client.create_execution(request=request_create_execution, timeout=120)
operation_result = operation.result()
# Create template
request_get_execution = GetExecutionRequest(name=operation_result.name)

while True:

  execution_status = client.get_execution(request=request_get_execution)
  if execution_status.state == Execution.State.SUCCEEDED:
    break
  elif execution_status.state == Execution.State.FAILED:
    raise RuntimeError("Execution failed")
  time.sleep(60)

I create a DAG on Airflow for schedule job. I got a error. This error is not common, about 1 error out of 5s runs. The under is log of this error.

The above exception was the direct cause of the following exception:

Can you give me some suggestion to investigate the issue, here?

Hi @ltduong,

The error messages that you are receiving all points to an internal error but with limited information about it. This kind of error usually indicates that there is something going on in the Google Cloud Server, it may be caused by a hardware failure, a software bug or a network issue.

You can also wait a little then try again as the error might get resolved on its own. Sometimes, internal errors are temporary and will go away eventually.

Here are some usable resources that might be of help.

Hope this helps.

Hi @lsolatorio ,

Thank you for your support,

I have some extra information, here.

- When we got this error in Airflow, the executor on Vertex AI kept running without any problems until finished. So, I guess that is a network issue.

- I tried to increase the timeout for a request. And try to retry and sleep (1, 2, 3, 4, 5 minutes) again, but I still have this problem.

MAX_NUM_RETRY = 5
retry = 0
while True:
    try:
        timeout = 600
        execution_status = client.get_execution(request=request_get_execution, timeout=timeout)

        if execution_status.state == Execution.State.SUCCEEDED:
            break
        elif execution_status.state == Execution.State.FAILED:
            raise RuntimeError("Execution failed")
        time.sleep(5)

    except Exception as e:
        retry += 1
        if retry >= MAX_NUM_RETRY:
            raise RuntimeError(f"Execution failed with too many retries: {retry}")
        time.sleep(60*retry)

Do you have any suggestions for me to try or investigate further?
