Open Script Errors :An internal error occurred during: "Launching Open Script".

Open Script Errors :An internal error occurred during: "Launching Open Script".

Some times we get an internal error in the open script during recording and playback of the script and open script  workspace stopped responding.

Error and exceptions : java.lang.NullPointerException

Resolution of this problem: 

a) Save the script and all the assets related to open script worksapce and close open script.

b)  delete the osworkspace directory  or rename it .

c) It is always advisible to rename it rather than deleting it , but in case renaming doesnt resolve the issue then it is recommendable to delete it (but backup before deleting it).
