    Hi Sean,

    Thanks for reaching out. That is quite peculiar. I notice that you are using 9.1.1 and also that a Compute Server Worker is involved. Can you first try upgrading to 9.1.2 and seeing whether you can reproduce this behavior? If the error persists, can you then explain a little bit more about your setup, i.e., how many workers are involved, what are you using the worker nodes for, where is your cluster set up, etc?


    Kind regards,
