How to avoid map-reduce error when tried to run at same time through script

Recently, I ran into an issue of map-reduce script tasks failing because of an existing map-reduce script deployment running in parallel.

I was triggering the map-reduce script from another script like this:

 let createMapReduceTask = task.create({
                    taskType: task.TaskType.MAP_REDUCE,
                    scriptId: MAP_REDUCE_SCRIPT_ID,
                    // deploymentId: MAP_REDUCE_DEPLOY_ID,
                    params: {
                        custscript_map_reduce_script: parametr
                    }
                });

I was getting errors initially when this map-reduce was already running in the account, and I tried to execute this again.

To avoid this error, I created multiple deployments of the script and commented the ‘deploymentId’ key in the task.create() function. The map-reduce worked correctly when I triggered it as many times until the total number of deployments.
