We have also created a SUPPORT ticket https://app.camunda.com/jira/browse/SUPPORT-6670 in order to track the progress of this issue. Here is an explanation for the issue: This error can occur if you store huge string or large amount of data in a variable of type "String". Internally, the process engine uses a VARCHAR field which has a limit of maximum 4000 characters (it varies for different databases) to store a variable of type String. If you need to store longer documents, you can tell the process engine to persist a String as a Java Serializable value. This can be done the following way using the Java API: import org.camunda.bpm.engine.ProcessEngine; import org.camunda.bpm.engine.RuntimeService; import org.camunda.bpm.engine.runtime.ProcessInstance; import org.camunda.bpm.engine.variable.Variables; import org.camunda.bpm.engine.variable.Variables.SerializationDataFormats; public class SomeClass { protected ProcessEngine processEngine; public void startProcess() { String aLongStringValue = repeat( "a" , 5000); RuntimeService runtimeService = processEngine.getRuntimeService(); VariableMap variables = Variables.createVariables(); variables.putValueTyped( " var " , Variables .objectValue(aLongStringValue) .serializationDataFormat(SerializationDataFormats.JAVA) // tells the engine to use java serialization for persisting the value .create()); // Start a process instance ProcessInstance processInstance = runtimeService.startProcessInstanceByKey( "testProcess" , variables); } protected String repeat( String string, int times) { StringBuilder sb = new StringBuilder(); for ( int i = 0; i < times; i++) { sb.append(string); } return sb.toString(); } } The snippet variables.putValueTyped( " var " , Variables .objectValue(aLongStringValue) .serializationDataFormat(SerializationDataFormats.JAVA) .create()); creates a process variables that is going to be serialized using standard Java serialization. The serialized byte stream is then stored in the database in a byte array field of arbitrary length. For general documentation on process variables and the different value types, please see the user guide https://docs.camunda.org/manual/7.11/user-guide/process-engine/variables/ Best regards, Garima
