Thank you for your help! Actually, i could've been wrong. Upon double checking, the last failure we saw may not have had the changes above. I will update you if we see this failure again (it's very intermittent for us).

Thank you for responding but it doesn't seem to help. Anything else we can try?

We are seeing intermittent errors while using jsreport 2.1.1:

A critical error occurred while trying to execute the render command: An error has occurred when trying to initialize jsreport (2). Duplicated entry for key samples (1).
caused by error (2) -> meta = {"disableExit":false}, stack = Error:
at instance.init.then.catch (/usr/local/var/jsreport/node_modules/jsreport-cli/lib/instanceHandler.js:31:29)
caused by error (1) -> stack = Error:
at persist (/usr/local/var/jsreport/node_modules/jsreport-fs-store/lib/persistence.js:173:11)

Could somebody please suggest what the cause of this error might be?

Thanks,
Vlad
