AriesFrameworkError: Agent has no public DID

[AlexTheDog0]

Hey,
I am new to SSI and testing snippet of code from here and also from here
Getting this error "AriesFrameworkError: Agent has no public DID". I understand meaning, but do not know what to do with it
P.S It seems to be easy to solve and sorry for disturbing with such obvious (maybe) tasks, but I am desperate

Hi @AlexTheDog0! Which version of AFJ Are you using?

@blu3beri any thoughts?

[AlexTheDog0]

@TimoGlastra

"@aries-framework/core": "^0.2.5"
"@aries-framework/node": "^0.2.5"

It seems I am doing something wrong whe registering DID in http://dev.bcovrin.vonx.io/
Can you help please about what exactly should I do?

[berendsliedrecht]

Hmm, is the seed registered correctly at http://test.bcovrin.vonx.io?
You can enter the "publicDidSeed" (abcabcabc12345678912332132345433) in the "Wallet seed" field on the page. Hope that helps.

[TimoGlastra]

@AlexTheDog0 if you can provide a repo that I can clone / yarn install / yarn run I'm willing to take a look!

https://github.com/oadamovskyi/aries-fm-agent

npm install
ts-node src/index.ts

P.S endpoint URL it`s just an empty server with 'Hello World' inside that are hosted on 3001 port

@TimoGlastra @blu3beri
Oh it is working...
It seems there was some typo
Sorry for disturbing with such tiny things
Thanks for your time
