Issuance fails

[GHkrishna]

I am trying to issue credentials by uncommenting LOCUST_FILES=locustMediatorIssue.py as suggested by Quickstart

However, I am encountering the following error,

connection = self.client.accept_invite(self.invite['invitation_url'])
TypeError: 'NoneType' object is not subscriptable

The error comes from,

@task
    def accept_invite(self):
        self.client.ensure_is_running()

        connection = self.client.accept_invite(self.invite['invitation_url'])
        self.connection = connection

Here, the invite is set as follows,

    @task
    def get_invite(self):
        invite = self.client.issuer_getinvite()
        self.invite = invite

But the invite when printed is 'None'

I have following config in .env as,

ISSUER_URL=http://issuer:8150
ISSUER_HEADERS={}

I also tried replacing the above with my ip, localhost, 0.0.0.0, 127.0.0.1. But there seems no change. Also I am not able to see any logs in the issuer container that are otherwise printed in case we do any such operations(like creating an OOB issuance) directly on the issuer agent

Hi @GHkrishna! Here's a list of things to try :) (in order)

• Pull for recent changes to main (git fetch && git pull)
• Follow the quick start instructions, including to put in the mediation URL, as well as anchoring a DID, creating a cred def, etc.
• ^Follow the remaining instructions + run the test :)

I was able to get everything working, but please let me know if you run into issues!

I tried with multiple machines of different configs(all linux), but still unable to run the demo.

I am facing the same issue as mentioned above.

Note: The above schemaID and CredefId is the one that I have created as per the instruction.

As per suggested in the video, I didn't get any error regarding the pickup protocol. Still tested it with both pickup V2 and implicit in load-agent/agent.ts. Still the same error.

Error

This is the error from locust for your reference,

From failures

From Exceptions

I see no reasons to why this must fail as per the documentation. I also had a look at the debugging section, but was unable to find anything helpful regarding this specific issue.

Another thing to note is, I tried by cloning the exact version of credo(afj-0.4.2, as per the package.json) into the root directory as suggested by the docs, as AFJ has now been updated to credo-ts. Can this be an issue?

Please let me know if there's anything required from my end to help debug the issue faster, this seems like a very interesting issue.

Update on this,

We were able to run the Quickstart with the following changes. I have created a PR #70 for this.

The issue was while setting the environment variables for Issuer type below,

ISSUER_TYPE = os.getenv("ISSUER_TYPE", "acapy")
VERIFIER_TYPE = os.getenv("VERIFIER_TYPE", "acapy")

Since, the ISSUER_TYPE and VERIFIER_TYPE was missing in the sample.demo.env the above code also failed to assign the default value for some reason. For now until we have a definite solution upon why the default values are not picked, we can add the types in env's as the PR

@anwalker293 can you please have a look at this?
