Rest /repository/process-definitions returns errorMessage': 'unknown type 'processDefinition' processDefinition'

[pcolot]

Using activiti 5.14, the following REST service is not fully working:

GET with http://localhost:8080/activiti-rest/service/repository/process-definitions
‍‍‍

The result is :

{
    "errorMessage": "unknown type 'processDefinition' processDefinition",
    "statusCode": 400
}
‍‍‍‍‍‍

In the tomcat 7 log :

but the following REST service is correctly working:

GET with http://localhost:8080/activiti-rest/service/repository/process-definitions/createTimersProcess:1:31
‍‍‍

returns:

{
    "id": "createTimersProcess:1:31",

    "suspended": false,
    "startFormDefined": false
}
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Am I correctly using the API Rest ? Unless how to get the list of all process-definitions ?


Best regards

The problem is that there's a process definition deployed with a form field type of process definition in it. To make this work, the REST application also needs to have this form type registered. Otherwise it throws the error you mention here.

Could you take an example?

Check the Explorer config where the form types are injected in the Process Engine beans.
