Hi team,

I got when trying to run the ReadmeExampleTest by using gradle build

The error is as below:

Do you know how to fix the issue in order to have

You can buy drinks: true

?

Thank you for your help, AD

Hey there!

Thank you! We have made a fix. Here is the working version - https://github.com/Luxoft/cordentity/tree/fix/example-test (it is almost the same except ReadmeExampleTest.kt:97).

Unfortunately, we're unable to merge it into master right now, because Cordentity is currently migrating to the HL Labs (https://github.com/hyperledger-labs/cordentity).

Hey @seniorjoinu, thanks for the quick updates. I managed to have it and get the result to true. But when I tried with other value of "BORN" to test invalid values, it still shows true (for example changing from 2000 to 2005). Do you have any hint for this?

Much appreciate for the help!

Hi @ADL-work Actually it's great that you bring it up. I just have checked the code and let me explain. Currently Indy covers only ">=" mathematical operations. However, they are working on "<" right now.

Let's take a look the example,

In line 89 Indy eventually compares for us 2000 >= 2000 which is true. However, if we change to 2005 we get 2005 >= 2000 which is also true.

Thus, to fix it we will migrate on the latest version as soon as "<" ready and will provide different mathematical operation on predicate building phase.

Sorry for that. And many thanks for your passion, very appreciate.

BTW @seniorjoinu could you, please, check my statement and finally confirm it.

Hi @alkopnin,

Many thanks for the explanation, I got it now. When I tried with "1999", it raised an exception and the return value is: false, which is clear now as (1999 >= 2000) is false.

Thanks and have a nice afternoon/evening 👍

i have the same issue and its clear that it fails in the predicate - but ... the predicate is not the issue. try to add an "attribute reference" into it.

org.hyperledger.indy.sdk.InvalidStructureException: A value being processed is not valid

i have validated and compared it to com.luxoft.blockchainlab.hyperledger.indy.AnoncredsDemoTest and here all is working..... it seems that additional entries in the request to indy-sdk

see test attachements AnoncredsDemoTest.json.txt shopping-schema.json.txt

i traced the error and I receive:

fixed bug above while removing unneeded "revocation" information. if "revocation" is available there is an SDK issue

patch-cordentity-master.diff.zip

i fixed it on top of master in https://github.com/hyperledger-labs/cordentity

lolo8304 commented 5 years ago

for all: sorry about my message - my mistake. I built "indy master --> 1.8.* but cordenity is only working with 1.7.0 so far (in master and developer branch)

all fine now
