Hello @Viraj Hudlikar 

Cleared both browser and instance cache. Same issue.

I checked the Dictionary Override for valid_to in the kb_knoweldge table but there are no overrides set.

I found some business rules related to the valid to date for knowledge articles. These were disabled to test and did not change.

We tested putting in a specific date in the default field and it did populate that date when creating a new article. However with the code written above it leaves it blank. Article Validity set on knowledge base and even when not set it should populate default of 2100-01-01 but it does not.

Tested running the script itself and it works, just when not being called during creating new or checkout out an article.

We are still looking into it.

Thanks.
