Above exception is coming when I try to execute below code,

final Deployment deployment = repositoryService.createDeployment().addInputStream(fileNamePath, fis)
                .name(deploymentData.getDeploymentName()).tenantId(deploymentData.getTenantId())
                .enableDuplicateFiltering(deploymentData.isEnableDuplicateFiltering()).deploy();

So here deploy() method throws this exception. When I debugged this in camunda code the exact place of this exception is from camunda class org.camunda.bpm.engine.impl.cmd.GetNextIdBlockCmd.execute(commandContext). The method is as below and here property is null, and because of this property.getValue() throws null.

  public IdBlock execute(CommandContext commandContext) {
    PropertyEntity property = commandContext
      .getPropertyManager()
      .findPropertyById("next.dbid");
    long oldValue = Long.parseLong(property.getValue());
    long newValue = oldValue+idBlockSize;
    property.setValue(Long.toString(newValue));
    return new IdBlock(oldValue, newValue-1);
  }

Solution

  • I got the solution to my problem.

    This exception is coming because the highlighted property next.dbid in the below screenshot was missing in my ACT_GE_PROPERTY table of camunda.
