Processes stuck because of process variable serializer not found

Camunda 7 Topics Discussion & Questions
1

Hello,

We are on Camunda 7.6.2 EE and applied required patches.

Most of the processes are working fine as expected except few processes getting stuck with below error

Error while evaluating expression: ${CSI_CONTIVO_IWWOD_RESPONSE}. Cause: ENGINE-03040 No serializer defined for variable instance ‘org.camunda.bpm.engine.impl.persistence.entity.util.TypedValueField@1a729a8c’

${CSI_CONTIVO_IWWOD_RESPONSE} is a string variable and declared as text in bpmn.

What would be the cause for this behavior?

Regards,
Manoj

Hi @manojkumar,

can you provide a failing test case which demonstrates the problem?

Best regards,

We found a camunda instance with old code base processing transactions from same database and causing these exceptions. We are seeing no issues after bringing down the instance with old code. Issue 3894 I posted earlier is also resolved. Thanks.
