For anyone looking for a workaround:

Once a workflow is started, the memo data cannot be updated at this time. If you need the capability to update information during the workflow execution, consider using search attributes instead, which can be updated and are indexed by Elasticsearch.1

To include memo data, you should specify it as part of the StartWorkflowOptions when initiating a workflow. This is applicable for both the Go and Java clients. If modifying existing information within a running workflow is crucial, leveraging search attributes would be the appropriate approach, with extensions via the UpsertSearchAttributes function suited for this purpose. However, this requires Elasticsearch support.
