You can fix this couple of ways either updating the corresponding node in DB as mentioned here by Sujit, or by running a simple javascript snippet at the repository to update the nodes(module.currentVersion) property as a script or in javascript console.

What if this occurs at your development environment using Maven SDK at startup. The repository is not up yet so you cant execute a script or is difficult to connect to H2 db instance and perform an update.

Alternatively try this :

At the root of your project execute
mvn versions:set -DnewVersion=1.0.19.02xxx

The issue should be resolved :-)

Alfresco workflow :

Ever noticed below errors?

http://localhost:8080/alfresco/service/api/workflow-instances/activiti$3422

Find the workflow id from the workflow console:

Error as below?

{
    "status" : 
  {
    "code" : 404,
    "name" : "Not Found",
    "description" : "Requested resource is not available."
  },  
  
  "message" : "09090002 Unable to find workflow instance with id: activiti$ContentApprovalFlow:1:5605",  
  "exception" : "",
  
  "callstack" : 
  [ 
      
  ],

  "time" : "Oct 9, 2019, 1:35:17 PM"
}

Solution encode the request and access like
http://localhost:8080/alfresco/service/api/workflow-instances/activiti%245905?includeTasks=true

    "description" : "An error inside the HTTP server which prevented it from fulfilling the request."
  },  
  
  "message" : "09090001 Wrapped Exception (with status template): null",  
  "exception" : "",
  
  "callstack" :

  "time" : "Oct 9, 2019, 2:24:32 PM"
