Hi @Pratyusha28 - the camunda-external-task-client-python3 package is a Camunda 7 package, not compatible with C8; pyzeebe is the opposite!
It is only supported in the Java client currently (pyzeebe is a community-maintained project, and is looking for a new active maintainer), but we do support job streaming. The Zeebe gRPC gateway also supports a long-running job streaming request. Or you can manually query for queued jobs via the gRPC gateway.
The Java client is making these gRPC calls, so you can look at the source if you’re interested in implementing your own version.
Hope that helps!
