BDR offline in UI Designer
Hi,
On a fresh installation of version 7.10.4 or 7.10.5, I have a message in the UI Designer instead of the BDM icon on the left, I have an icon with a message on the right that says in french something like : unable to connect to business model, try to restart Studio to solve the error.
Restarting the studio does not change anything, neither reinstalling.
When I check in dev mode in the browser I can see a request to the business data repository in error :
message Connect to 127.0.0.1:49967 [/127.0.0.1] failed: Connection refused: connect
description The server encountered an internal error that prevented it from fulfilling this request.

Otherwise, everything works fine, I can make changes in the UI Designer and deploy process.
It just seems that the link between Business Data Repository for the UI Designer is dead.
Platform : Windows 10, Firefox, same problem with other browsers
I have tried to make an exception in Windows Defender for the Bonita directory, even stop the FireWall and threat protection completely with no result.
Does anyone know what could cause the behaviour ?
Thanks in advance
Attempting to access : http://localhost:57813/bdm/graphical
results with a 404 error
Comments
Those are chosen at startup by the Studio (it takes random available port), so you need to check in the studio logs which port is used. (Starting RESTLET server on port ????...)
If you cannot access the endpoint then there is a network configuration on your machine that block the access. Are you admin of your machine ? Do you run a specific antivirus ?
If yes I suggest to open the windows Firewall panel, go to inbound rules, search for all rules containing 'bonita', 'java', 'nodejs' and 'OpenJDK' and delete them.
Then restart the Studio, windows should prompt firewall dialog, allow everything and see if it works.
Well,
I am admin of my laptop, no other AV than Windows Defender.
I reseted the firewall again to remove all rules.
Here is the message from the log :
!ENTRY org.bonitasoft.studio.designer 1 0 2020-06-25 11:10:54.837
!MESSAGE Starting RESTLET server on port 64105...
So I tried :
http://localhost:64105/api/workspace/status/
result :
Studio is alive
http://127.0.0.1:64105/api/workspace/status/
result :
Studio is alive
In the end, I still have the error with the UI Designer :
http://localhost:57813/bonita/bdr
it returns error 500
Connect to 127.0.0.1:57812 [/127.0.0.1] failed: Connection refused: connect
Comments
What about http://localhost:57813/bdm/graphical ? It's weird that when connecting to port 57813 error message talk about port 57812.
There is a shortcut in the studio that let you open a console view. Once the studio is started you have to press Alt+Shit+Q release and then C, then you can choose the process to monitor using the blue screen icon on the top right of the view. Select the data repository process and check if there is more error than in the log file.
Are you using a network proxy ?
| I use a VPN and there is a proxy on the network connection I am provided with.
There is a good chance that it messes up the communication between the Studio and the service, thus the service kill itself as it doesn't manage to reach the Studio. I'll fill a bug, and we will try to reproduce the issue. I'll keep you in touch. In the meantime you can install a Studio on a personal machine (if possible) and acknowledge that when you are not behind a proxy the service works properly.
Thanks for your help

Hi Guillaume,
That's weird, is it possible that your firewall is blocking the access to some studio port ?
Can you check your firewall configuration and ensure that there is no deny rule for BonitaStudio ?

<p>Hi,</p>
<p>I don't see any Deny rule, only accept for bonitastudiocommunity.exe.</p>
<p>I even reseted entirely the firewall and re accepted the requests that pop up when starting bonita, just to be sure.</p>
<p> </p>
<p> </p>
<p> </p>
Does it happen with a very basic BDM ? (Just one object with default attribute)
<p>It happens even with an empty BDM.</p>
<p> </p>
Here is the studio log also, there is definitely something stopping the BDR :

Can you access the following endpoint after starting a Studio: http://localhost:56430/api/workspace/status/ ? You should have a response 'Studio is alive'
Can you also try with: http://127.0.0.1:56430/api/workspace/status/ ?
If one of the above is not working properly that's the cause of the issue as the Data Repository service will shut down if this endpoint is not successful.
Thanks
