Bug: Inputs not downloaded to Service

[Konohana0608]

I see an old monster rearing its head. When the service starts, it tells me that apparently all inputs are downloaded successfully. But then the service still gets stuck since i have an AwaitInputs function that checks if all the required files are available. When investigating I saw that even if the platform acts as if all inputs were downloaded, I see that in the inputs folder, the files are not there. Then of course the service will get stuck.....

I thought that this was taken care of a long time ago and it is a big deal if that is not working when our platform is all about building pipelines that propagate files to subsequent services....

I can only fix that by disconnecting and reconnecting the inputs.....

but that is not an option for our users since they have the application in app mode and we shouldn't require users to have to manually disconnect and reconnect stuff....

Me and @matusdrobuliak66 investigated this issue and we were also able to reproduce it on osparc.io.
We connected two jupyter notebooks

and created some output files in the first one. Already then we discovered that some (but not all) of the outputs were not available in the inputs folder of the second one. We tried to restart the second service and again saw that some (but not all) inputs were available in the second node.

Thank you for investigating @bisgaard-itis and @matusdrobuliak66 . I realized that I forgot to add the study and service ids so here it is:
deployment: tip.science
study_id: d3084df0-4298-11f0-b6c5-0242ac178f44
service_ids:
ddac5ea3-48f2-5f07-ba14-206a54dbeb41
253e0944-a7be-4f25-a52b-494521fbb00c

I hope that helps.
