Unirest.config() is null

[jmechamFD]

When trying to set the cookie specs with the line: Unirest.config().cookieSpec(CookieSpecs.STANDARD) I receive the error: java.lang.NullPointerException: Cannot invoke "kong.unirest.core.Config.cookieSpec(java.lang.String)" because the return value of "kong.unirest.core.Unirest.config()" is null.

I can't find any mention online of anyone else having this error and the docs show this is how you edit the config so I'm not sure what I'm doing wrong in this case.

• My build.gradle.kts file has this import although I've gotten this error with the most recent version v4.4.5 as well : implementation("com.konghq:unirest-java:3.14.5")
• I just import Unirest in my class using import kong.unirest.Unirest
• Then the call Unirest.config() will return null.

There are a few strange things here.

1. You say you are using Unirest 3.14.5 but then you also say you are using kong.unirest.core.Unirest which is not a package that exists in the 3 line. Unirest there is just kong.unirest.Unirest. Do you maybe have Unirest 4 as a transient dependency? Unirest 4 was a major overhaul so it was moved to not conflict with Unirest 3.
2. Per the Unirest code it's mostly not possible to have a null config unless you explicitly created that state in some way. There are only two uses of the Unirest constructor in the library itself and they both provide a config object

I apologize for the confusion. I originally was using version 3.14.5 and was getting this error. I upgraded to the latest version v4.4.5 to try and fix this error and I still got the same error and that's when I copied the Null Pointer Exception. I have verified there is only one version of Unirest being imported by my application. I currently have reverted it back to version 3.14.5.

I did some more debugging and figured out this behavior occurs exclusively in my unit tests in the methods I'm calling Unirest.config().cookieSpec(CookieSpecs.STANDARD). However this method works as expected when I run my application normally. It also appears the .config() method is not the only method returning null.

are you using a mocking framework? Including the Unirest mocking library?
