Hi AJESH-CR, thanks for using the contraect-maven-plugin :) The issue you face is due to an issue with your maven config: can you please delete the <config></config> within the configuration-tag and try again Regards, Mitch

[AJESH-CR]

Thanks for the support Mitch, Applied the fix, now I faced another issue

SEVERE: Unhandled exception

Thanks again Mitch.

Hi @AJESH-CR, sorry for the circumstances. This is a problem with the configuration of our SDK and will be fixed in upcoming versions. You are probably running or using the http compiler which has an updated endpoint that returns more attributes than expected.

You have two options in my opinion:

1. run the http compiler locally (e.g. via docker) in the version we have used in our showcase application (there we have a docker-compose file which runs a local node and compiler)
2. take a look at https://stackoverflow.com/a/25718495/2343286 and try to fix this via configuration in your application

Again, sorry! We are currently working on the 3.0.0 release which will fix this and also introduce some other breaking changes as well as support for new features that are coming with the Iris hardfork. (e.g. PayingForTx).

Thanks, marc0olo.

I got this issue while I run the HTTP compiler locally via docker using the below image

REPOSITORY                TAG                 IMAGE ID            CREATED             SIZE
aeternity/aesophia_http   latest              bb0dc6751804        9 months ago        180MB

And configured the URL http://localhost:3080 in the compilerBaseUrl element.

Edit 1

• I changed aeternity/aesophia_http docker image version to v4.2.0 from latest. Now It's worked fine.

Thanks marc0olo & Mitch

glad you got it solved! :-)

stay tuned for upcoming updates. there will be some breaking changes and you shouldn't face this problem anymore by default
