problem with running example parallel futures using batchtools_lsf

[haibol2016]

I am trying to run the example code in the future.batchtools Git Hub README, as follows.
But I failed due to error message shown below.

Could you help me out?
Thank you.

Haibo

library(future.batchtools)

plan(batchtools_lsf(template = "lsf.tmpl", workers = 2,
                    resources = list(walltime = 3600*8, num.cpu = 4,
                                        mpp = 1024*4, queue = "long")))

x %<-% { Sys.sleep(5); 3.14 }
y %<-% { Sys.sleep(5); 2.71 }
x + y

I got the following error message inconsistently

1. err message 1:

Error: Log file '/project/umw_arthur_mercurio/Haibo/InPAS/.future/20211220_104348-sqIN0l/batchtools_2107070426/logs/job74e5f3ce70dd44fe91a775b79b221d03.log'
for job with id 1 not available

2. err message 2:
   Error: BatchtoolsExpiration: Future ('') expired (registry path /project/umw_arthur_mercurio/Haibo/InPAS/.future/20211220_104348-sqIN0l/batchtools_290284087)
   .. No logged output exist.

The contents of my lsf.tmpl file is as follow:

## Default resources can be set in your .batchtools.conf.R by defining the variable
## 'default.resources' as a named list.

#BSUB -n <%= resources$num.cpu %> # minmal numbers of processors required for a parallel job
#BSUB -R rusage[mem=<%= resources$mpp %>] # ask for memory per cpu
#BSUB -J <%= job.name %> # Name of the job
#BSUB -o <%= log.file %> # Output is sent to logfile, stdout + stderr by default
#BSUB -q <%= resources$queue %> # Job queue
#BSUB -W <%= round(resources$walltime / 60, 1) %> # Walltime (LSF requires minutes, batchtools uses seconds)
##BSUB -M <%= resources$memory %> # Memory requirements, e.g. "5000KB", "500MB", "5GB" etc.
#BSUB -R "span[hosts=1]" # All hosts on the same chassis"

## Export value of DEBUGME environemnt var to slave
export DEBUGME=<%= Sys.getenv("DEBUGME") %>

<%= sprintf("export OMP_NUM_THREADS=%i", resources$omp.threads) -%>
<%= sprintf("export OPENBLAS_NUM_THREADS=%i", resources$blas.threads) -%>
<%= sprintf("export MKL_NUM_THREADS=%i", resources$blas.threads) -%>
