  • Amazon S3 downloader does not work while first run and succeed only while the second run

I'm working with FMEServer.

I developed a small workbench that connects to s3, reads the content of some folder and downloads it into FME resource folder. The problem with downloading occurs only while first running. I get the following error:

FAILURE

java.lang.Exception: COM.safe.fmewebservices.FMEWebServiceException: COM.safe.fmeserver.api.FMEServerException: QSInvalidRequest

When I repeat a job, right after that, the job is done successfully.

In both cases, engines are turned on.

My workflow is as follows:

Any idea of solving this problem?

You say "engines", so that implies there's more than one. Did these jobs run on different engines and if so, could there be a difference between them?

I'm not aware of the engines state. I use the default set that FME allocates to me. I turn them on with FME GUI Engines & Licences section. S3 downloader is the only workbench that fails with the first run. Others do well.

HI @przegee,

Which versions of FME are your using (Desktop & Server). In general, I would recommend using the S3Connector instead of the legacy transformers if possible:

I use FME Server 2018.1.2.0 and FME Desktop 2018.1.2.0.

 

It looks like s3conector is not recommended anymore in my version.

Have you tested it in the 2019 version?

Yes, it is released in 2019.0 and the recommended transformer to interact with S3
