How to display variable in form but not edit the value in Camunda?

Camunda 7 Topics Discussion & Questions

In a Camunda proces I have this script in a User task:

<form role="form">
    <script cam-script type="text/form-script">

        camForm.on('form-loaded', function() {
            camForm.variableManager.fetchVariable('Request');
        });

        camForm.on('variables-fetched', function() {
            $scope.RequestJson = "{\n" + atob(camForm.variableManager.variableValue('Request')).split('\n').splice(1).join('\n');
        });
    </script>
    <pre><code>{{ RequestJson }}</code></pre>   
</form>

When viewing the form the data is correctly formatted as I want it, the data should not be edited in any way.

The form is part of an user-task, the user should see the data, do some stuff in other system and then Complete the task and the process should finish.

When I click the Complete button, I get an error: Cannot submit task form e6bf6b22-33df-11eb-951d-d0577b0fc0e4: ENGINE-17007 Cannot set variable with name Request. Java serialization format is prohibited

I know what the error means, but I don’t want it to serialize the data, I just want the process to complete/finish, the form-data is irrelevant. (this is the last step in the process)

How can I achieve this by editing the Form?

You probably want to remove it before submit, as discussed in this thread:
