Not a function issue, in older Reader versions

[NikosGiann]

Hello to community,

i am dealing with the following problem.
I have developed a form using AEM Forms (Designer 6.4) where at some point i am using the Object.keys

While this works fine in both Acrobat Pro DC and Reader DC, i have complaints from some users that they get the Object.keys is not a function error.
The user is using Adobe Acrobat XI (version 11.0.23).

Before telling them to upgrade the Acrobat to DC, i would like to know from which version the Object.keys is introduced, so as to have a minimum Adobe Acrobat version, in the specifications of using the form.

Thank you

From the DC version. I would change the code to work with older versions, instead of asking the users to upgrade.

Thank you very much for the reply.

Could i add that, some users state they have Adobe Acrobat Reader DC and Adobe Acrobat XI Pro
and while they use they DC they get the same error.
Is this possible?

Maybe it was introduced during one of the updates. To ensure backwards compatibility I would not rely on it to work.
