No output file after running slurm dmtcp job

Question

After running a SLURM job, I can't find the output file anywhere. The squeue command shows that the job is executing correctly, and there aren't any error logs on the current directory, from which I call the sbatch dmtcp-slurm.job. Could this be happening because theere's a error which prevents the output file from being created?

dmtcp-slurm.job:

#!/bin/bash
# Put your SLURM options here
#SBATCH --time=00:15:00           # put proper time of reservation here
#SBATCH --nodes=2                 # number of nodes
#SBATCH --ntasks-per-node=4       # processes per node
#SBATCH --mem=1983                # memory resource
#SBATCH --job-name="dmtcp_job"    # change to your job name
#SBATCH --output=dmtcp.out        # change to proper file name or remove for defaults
# ? Any other batch options ?

# Start DMTCP coordinator on the launching node. Free TCP port is automatically

# as a wrapper around dmtcp_command.  The script tunes dmtcp_command for the
# exact dmtcp_coordinator (its hostname and port).  Instead of typing
# "dmtcp_command -h <coordinator hostname> -p <coordinator port> <command>",
# you just type "dmtcp_command.$JOBID <command>" and talk to the coordinator
# for JOBID job.

# 2. Launch application
# 2.1. If you use mpiexec/mpirun to launch an application, use the following
#      command line:
#        $ dmtcp_launch --rm mpiexec <mpi-options> ./<app-binary> <app-options>
# 2.2. If you use PMI1 to launch an application, use the following command line:
#        $ srun dmtcp_launch --rm ./<app-binary> <app-options>
# Note: PMI2 is not supported yet.
# 2.3. If you use the Stampede supercomputer at Texas Advanced Computing Center
#      (TACC), use ibrun command to launch the application (--rm is not required):
#        $ ibrun dmtcp_launch ./<app-binary> <app-options>
