Hi,

Using:
Neo4j Desktop Version: 1.3.10
Neo4j Instance: 4.1.3-enterprise

running on Mac OSX Catalina

I have uninstalled and reinstalled but keep getting the error message above when I try to connect to a postgresql instance.

I'm not adequately java savvy to even know where that class should be, sorry, or how to replace it?

cheers

Ben

can you share a screenshot of the error?

I am getting the same error.

Using:

  • Neo4j Desktop Version: 1.3.9
  • Neo4j Instance: 4.0.4-enterprise

It won't help (I suspect) for me to post another screenshot, but I did find:

@benmadin @J-Krush

Thanks for reporting this issue.
We have noticed that when downgrading to a previous version of Neo4j Desktop (1.3.4) this problem does not occur.
We are still investigating.
In the meantime, could you please downgrade to Neo4j Desktop 1.3.4? You can download it here

Thanks!

Mauro

Thanks a lot for the reply @mroiter-larus. I can confirm that the downgrade to Neo4j Desktop 1.3.4 works.

Greetings Great Graph People ^_^
Just another +1 here.
Same on Windows 10 Pro.
And same workaround with v.1.3.4 Neo4j Desktop works perfectly

Cheers,
Denis

It's the same for Ubuntu 20.04!

Hi @benmadin @J-Krush @agfagerbakk,

The attached package should solve this issue.
Could you please try it with the latest Neo4j Desktop release and let us know if everything works as expected?

Thanks in advance!

neo4j-etl-ui-1.5.0-release.tar.gz

I have just updated to the latest Desktop release 1.3.11 but I still get the same error.

@jonaswascheroh We have not yet released the ETL tool fixed version. In the meantime, could you please install the ETL tool version i shared here?

Thanks,

Mauro

@mroiter-larus Yes it worked.

Thanks!
Jonas

@mroiter-larus Not sure if I should rather open a new issue but with the package you provided it seems that no relationships are created.

......
- Creating relationships of type AREA_SERVICE
- Creating relationships of type EMPLOYEE_SERVICES
- Data imported with errors. Below the list of errors.
- For exception NullPointerException we got the following errors:
- 
Process failed null

Do you have any idea what this means?

Jonas

@jonaswascheroh can you open a new issue with the details of your dataset if it's possible?

Hi, I update the desk image and updated etl tools, but it still can not working/

@ShunyangLi Did you use the released version of the ETL tool or the self-builded temporary package provided here?

Thanks,

Mauro
