[Bug] Error while creating ApiContext with the Java SDK

BLACKBEAR-B-V-Red-Owl

Hi All,

Ever since I updated the version of the bunq sdk_java dependency (1.10.16->1.13.1, due to connection issues https://github.com/bunq/tinker_java/issues/16). I get the following error " BEGIN_OBJECT but was BEGIN_ARRAY" when invoking the ApiContext.create method. For some reason this error only occurs with my production api key but not with any sandbox api key. I tried creating a new production api key but without success. I was hoping that someone could help me with this.

Stacktrace:

BLACKBEAR B.V. Hello!

Thanks for reporting.

This is a known issue. I've forwarded this issue yesterday to the product owner.

Bastiaan

Looks like this error is caused by the following line in the code of the SDK:
https://github.com/bunq/sdk_java/blob/develop/src/main/java/com/bunq/sdk/model/generated/endpoint/UserCompany.java#L177

I think this type is not correct, because it's a List and not an Object.

@Bastiaan Do you mean that the documentation is not correct? The documentation clearly lists it as an object.
For reference, we get the same error in our application and we directly call the API without any SDK.

Any update on this please?

Hey everyone! 👋

The issue won't be there tomorrow morning. You don't need to do anything on your side.

Nils-indigo

As this is a breaking bug for some companies. I've made a fork that fixes the above problem.
https://github.com/NilsTellow/sdk_java/
It can be pulled from JItpack. Same as Bunq SDK.
https://jitpack.io/#NilsTellow/sdk_java

Keep in mind that this a temporary fix, as I do not know what they will change in the API for the bug fix.

Hey, thanks for the quick responses and the quick solution, the error above is resolved. However I now get a
com.bunq.sdk.exception.BunqException: Response verification failed Exception when connecting with the API Key. Do you know what could be a reason for this?

BLACKBEAR B.V. What SDK version are you using?

BLACKBEAR-B-V-Red-Owl

Lexy 1.13.1

BLACKBEAR B.V. We cannot reproduce this problem (we've tried both sandbox and production). The issue must lie in something else.

v1.13.1 works for me, running stable now past 24 hours. Thanks!
