Question

Hi I am working with `S3Result` and receiving a ```botocore errorfactory NoSuchKey An error occurred NoSuchKey when calling the GetObject operation The specified key does not exist``` Which upon further research it can be anything including a permission error I tried different buckets with settings The credentials are stored as AWS CREDENTIALS in prefect cloud With the config toml set to use cloud secrets ``` cloud use local secrets = false``` Switching back to `result handler` argument with `S3Result` subclass did work And combining `result handler` with `target` does not Is there something different in the way that credentials are handled between `result` and `result handler` The new prefect is really nice slightly smiling face

Hi itay could you share the code you used to initialize the `result handler` and the `result`

itay livni · Answer

`tsx imb res = S3Result bucket= tsx moc bcp `

itay livni · Answer

``` task max retries=3 retry delay=timedelta seconds=1 In production this will be change to 20 minutes result handler=tsx imb res target= task name today state handlers= imb handler error handler ```

itay livni · Answer

Works with `target` commented out

Chris White · Answer

Ah The `result handler` kwarg is now deprecated so you should instead try ``` result=tsx imb res ```

itay livni · Answer

Right that does not work

itay livni · Answer

That is the problem

Chris White · Answer

ahhh interesting OK so this might actually be a bug with our `exists` logic on the `S3Result` type Would you mind sharing this example code + the traceback you re seeing Sorry about that

itay livni · Answer

Actually it looks like I am not using `target` right ``` 2020 05 16 21 31 37 INFO prefect FlowRunner | Beginning Flow run for Our first flow 2020 05 16 21 31 37 INFO prefect FlowRunner | Starting flow run 2020 05 16 21 31 37 INFO prefect TaskRunner | Task tsx url Starting task run 2020 05 16 21 31 37 INFO prefect TaskRunner | Task tsx url finished task run for task with final state Success 2020 05 16 21 31 37 INFO prefect TaskRunner | Task get tsx moc imb Starting task run 2020 05 16 21 31 38 ERROR prefect TaskRunner | Unexpected error NoSuchKey An error occurred NoSuchKey when calling the GetObject operation The specified key does not exist Traceback most recent call last File home ilivni miniconda3 envs py37moc lib python3 7 site packages prefect engine runner py line 48 in inner new state = method self state args kwargs File home ilivni miniconda3 envs py37moc lib python3 7 site packages prefect engine task runner py line 651 in check target if result exists target prefect context File home ilivni miniconda3 envs py37moc lib python3 7 site packages prefect engine results s3 result py line 167 in exists Bucket=self bucket Key=location format kwargs File home ilivni miniconda3 envs py37moc lib python3 7 site packages botocore client py line 316 in api call return self make api call operation name kwargs File home ilivni miniconda3 envs py37moc lib python3 7 site packages botocore client py line 626 in make api call raise error class parsed response operation name botocore errorfactory NoSuchKey An error occurred NoSuchKey when calling the GetObject operation The specified key does not exist 2020 05 16 21 31 38 INFO prefect TaskRunner | Task get tsx moc imb finished task run for task with final state Skipped 2020 05 16 21 31 38 INFO prefect FlowRunner | Flow run SUCCESS all reference tasks succeeded```

`target= task name today `

Chris White · Answer

your code looks alright to me actually including your `target` specification I think this exception catching logic here is flawed <https github com PrefectHQ prefect blob master src prefect engine results s3 result py L169>

Chris White · Answer

it s possible this was tested on a different version of `boto3` or something we ll need to investigate a little deeper

itay livni · Answer

Cool Let me know if you need anything more
