Dear Massimo,

Here is the comment from the Object Storage GE owner, incase this comment did not reach your inbox:

"From what I understand, the issue is that there is incorrect documentation in the tutorial https://edu.fiware.org/mod/scorm/view.php?id=723. I am unable to access https://edu.fiware.org/mod/scorm/view.php?id=723, and it seems to have been removed.

I do not know what was the content of that tutorial. All current tutorials are accessible through https://edu.fiware.org/course/view.php?id=130. Do you perhaps mean https://edu.fiware.org/mod/scorm/view.php?id=823?

It seems that certain operations through the portal or CDMI convert objects to base64.

I recommend to not mix the access methods. Either use only the native Swift interfaces as presented in the courses on https://edu.fiware.org/course/view.php?id=130 or use only the portal interface."

Therefore the ticket is closed.

Dear Kalman, could you take a look at this issue again? It seems the problem is reproducable with example in the Object storage tutorial.

It happens when you download an object through the portal, after having uploaded it through the code of the tutorial. Could you kindly try to see if you observe the same behavior with your setup?

Thanks,

ilknur

comment from Massimo

"The problem only if i download object from portal.
I upload the object as a tutorial and download always as tutorials without problem, but If I try to download the object from the portal can not.

If upload object through the portal I can download it from the portal without problem.

upload object command and code --------> download object command and code but no portal

upload object portal ----------> download object portal"

Dear Massimo,

Just a question, regarding “I am attaching also a piece of code that I used node js and that the same problem that occurs using the procedure of the tutorial.”..

When you use the procedure of the tutorial, do you mean you have the problem also when downloading through the command line? Or only when you download the object through the portal?

Thanks,

ilknur

The question now is related with the Object Storage course. Could you assign the ticket to the owner of this GE? Thanks

Dear Alvaro,

Here is additional info from Massimo:

"I tried the command that has shown me and everything works but it is not practical to convert a large file and then send it in base64.

To send the file without converting it into base64 I used the steps in your course online at this address:
https://edu.fiware.org/mod/scorm/view.php?id=723

if it isn't a problem related to my account as Wstore, and follow the tutorial able to replicate the problem : The file is loaded in object storage correctly, download correctly throw command but not download from web.

Fortunately not an issue that affects our project wanted to understand why this was happening I am attaching also a piece of code that I used node js and that the same problem that occurs using the procedure of the tutorial.

Source code node js
-----------------
var token = req.session.token_objst;
console.log(token);
var filename = "filename";
var user = "username";
request({
method: 'PUT';
headers:

,
uri: 'http://148.6.80.5:8080/v1/......./' + user + "/" + filename,
multipart: [

]
},
function (error, response, body) {
if (error)

console.log('Upload successful! Server responded with:', response);
});
---------------------------------------

Thanks a lot"

Dear Massimo,

Emailing you the response from Alvaro just incase you were not able to get notified through the JIRa system:

"Hi,
I'm trying to reproduce the problem but I can't.
I'm uploading an object using a curl request:
curl publicURL/container/object -X PUT -H "X-Auth-Token: token" -d '{"mimeType":"mimetype","metadata":{},"valuetransferencoding":"base64","value":"value"}'
and then downloading it succesfully from the cloud portal.
Please, check that you are using the correct body. If not, contact the owner of the specific node you are using."

Could you kindly let us know if you can download objects if you upload them using a curl command like Alvaro's? can we close the ticket?

Thanks,

ilknur

Dear Massimo,

Can we close this ticket? Are you able to download the object if you upload it using a similar command as the one Alvaro used?

Best regards,

ilknur

Dear Alvaro,

Is the info Massimo provided sufficient for you? Can you kindly help? Thanks,

ilknur

Good morning
I have attached to this mail the images of the procedure that i used to
load the object in objectstorage (Upload-1, Upload-2, Upload-3), the image
of the result (Result-1) and the image of the procedure to download the
object from the web (download) the result of this procedure (error) is seen
in the result-Download, the wheel of wait is always visible and does not
display the download window.

I hope it is clear what the problem is, as I wrote earlier discharge if the
object using the tools indicated in the figures and I can use the GET
command to download the object correctly.

Thankyou
Massimo Corna

Dear Massimo,

Alvaro is asking for an example of the code/command you used to upload the object so he can reproduce the issue.

Here is his comment from Thursday, incase it was not delivered to you through JIRA:
"Hi,
the only tests I performed are downloading objects that have been uploaded using the cloud portal. It is working also for you, right?
could you send me a complete example of the curl request to upload an object?"

Please kindly reply to this email (adding me to cc) so we can further investigate the issue.

Thanks,

ilknur

Hi,

the only tests I performed are downloading objects that have been uploaded using the cloud portal. It is working also for you, right?

could you send me a complete example of the curl request to upload an object?

Dear Alvaro,

Are you the owner of the Cloud portal? Would you be able to check the issue reported about downloading objects from the portal?

Thanks,

ilknur

The user reports that direct calls to the Object Storage work OK. it is only when going through the fiware web interface that there is a problem. I suggest to forward this issue to the fiware portal component, so they can check out the web interface.

Btw, since the system does not allow me to change the reporter of the bug, Massimo won't be able to see your response in the comments. Could you also kindly use the email menu on top right most corner on this page and email massimo.corna@krill.eu with your comments?

Thanks in advance,

ilknur

Dear Kalman,

Could you kindly provide some assistance to Massimo? He is from TeachByApp, a beneficiary SME of the FI-ADOPT accelerator.

The related screenshots of the error he is getting is in the main ticket from the coahing help desk. HELC-1077.

Thanks in advance for your help.
