    Warning, if the script takes longer than 2 minutes to execute, a nodered timeout error may be shown even if the script is executing correctly. If the timeout occurs, nothing is returned from the nodered. Alternatives for scripts that have an execution time greater than 2 minutes are: write the results to other APIs, increase the timeout time in nodered settings (this cannot be done if you use nodered on the snap4city platform)
