We have created an EEM script(attached it) in Lab, it worked fine. When we tried to implement it in Production router then the output of the action 2.0 comes out to be blank. The only difference b/w Production and Lab router is IOS. I have attached the o/p of working/non working. Any suggestion on this is highly appreciated.
LAB IOS : c3900-universalk9-mz.SPA.154-3.M3.bin
Production IOS : c3900-universalk9-mz.SPA.154-3.M4.bin
There are likely many more differences between your lab and production. I'm betting the configuration is very different. Perhaps you have AAA in production and not in the lab. If you do, the show command in question may not be authorized. Try configuring your applet with "auth bypass" at the end of the applet line and see if that works as expected.
