Duckling inconsistent result

Question

I am using Duckling for one of my projects to extract dates from given sentences. Initially, I pass the sentence to spaCy, which returns the substring falling under the DATE entity (for example, 'last week'). Then, I pass this substring ('last week') to Duckling, which provides the respective result.

Everything was working fine until I started encountering this error:

I am sending three subsequent requests to Duckling(through django api)[doing load api testing by creating collection with the above 3 request and running for 5 virtual users].

any advise will do good!!
