Error code: InternalError, Http status code: 500 while testing an experiment

Question

Creating a very simple experiment with just a Dataset, followed by a simple regresion using an Execute
R Task , I get an internal server error while testing the published experiment
Hitting run everything goes smooth and I can see all data,but when i hit 'test' from the web services dashboard
right after publishing,I get this:
Error code: InternalError, Http status code: 500, Request id: d87e2d01-16ef-4ac9-8a5d-a58d41aab2d4, Timestamp: Tue,

How can I handle this ?
Thank you in advance.

Hi Shreyas!
Are you familiar with the tryCatch() function in R? in your error condition, you can return the error message a bit more cleanly as shown in the following code snippet. FYI one common error we see is R scripts that are not able to handle a single-row input
or with mismatched data types.
tryCatch({
# Do what you want in here
maml.mapOutputPort("data.set");
}, error = function(e) {
data.set = data.frame(errormsg = conditionMessage(e))
print(conditionMessage(e));
maml.mapOutputPort("data.set");
