Problem description

Describe what you did in console that led to the error. Please provide a description of what actually happens. Be descriptive: “it doesn’t work” does not describe what the behavior actually is. This will help us with reproducing the problem.

Steps to reproduce

Please describe steps to reproduce starting from the first action.

Hello @Vinod_Sahu,

Please provide steps to reproduce this error, because I was able to create a new Codeless Timer in your app without any errors (already removed it).

Regards,
Olha

Sorry, I can create timer but issue with scheduling. When i am trying to call timer frequently in seconds getting error

As of now we want to run timer every 5 min

I’ve created an internal ticket BKNDLSS-23824. We’ll investigate this issue as soon as possible.

Regards,
Olha
