Hello Csaba,
it is not possible to downgrade from 0.9.0 to 0.5.4.
Catena-X did a major breaking update with its 24/05 release which reflects in dataspace in the Jupiter release that became operational in Oct. 2024. The final connector version that was provided for the Jupiter release was 0.7.6. All versions prior to 0.7.0
are not compatible with the current dataspace and all versions prior to 0.7.6 are not recommended to be used in the dataspace.
Concerning documentation, there is general documentation in the upstream Eclipse Dataspace Components repository. This documentation is not version specific. Each version has release notes in the Github Release item. There are migrations guides in the docs
folder of the tractusx-edc repository and alongside a management-api walkthrough which you find in a matching fashion in the tags of the corresponding version.
Mit freundlichen Grüßen / Best Regards

Betreff: [tractusx-dev] Errors beause of EDC downgrade from 0.9.0 to 0.5.4
Hello Guys,
At our company we had to downgrade the EDC from 0.9.0 to 0.5.4 our apps throws this exception below
(where mainly caused by empty config properties)
Caused by: java.lang.reflect.InvocationTargetException

So, my question is :
Is there any source where I can check what properties needed to 0.5.4 ?
Is there any documentation for specific releases or we only have changelog ?
What is the best way to putting together a small dataexchange with version 0.5.4 ?
Thanks in advance,
Csaba
