Environment (Required on creation)

Reproduced with

• Camunda 7.22.0
• Camunda Run
• H2

Description (Required on creation; please attach any relevant screenshots, stacktraces, log files, etc. to the ticket)

When starting a batch operation to set variables, we can filter process instances by query. When filtering the process instances by a variable of type Date, the query returns a result, but there is an error when the batch is executed.

Steps to reproduce (Required on creation)

• Take any process definition and set a date variable to an instance
• Go to Batch Operations in Cockpit and select Set Variable
• Select the query option to filter for process instances
• Set variable: variableName = 2024-10-17T13:55:00.000+0200 filter (depending on the date you set in the variable)
• Specify a variable to set with the Batch and execute the Batch.

Observed Behavior (Required on creation)

• There is an error when executing the dialog

Browser console log:

{
  "type" : "BadUserRequestException",
  "message" : "processInstanceIds is empty",
  "code" : 0
}

Error displayed in Cockpit:

Expected behavior (Required on creation)

• There is no error and the variable is set via Batch to all process instances found by the query.

Root Cause (Required on prioritization)
