Tutorial step to create the ledger fails #7

Closed maxweber closed 8 months ago

maxweber commented 8 months ago

Hi, I'm trying to follow the tutorial. Here are the steps I did:

git clone https://github.com/fluree/dataset-academic-credentials.git && cd ./dataset-academic-credentials

To start the Fluree server I run:

docker run -p 58090:8090 -v `pwd`/data:/opt/fluree-server/data fluree/server

In a second attempt, I also used docker pull fluree/server beforehand to ensure that I have the latest version. And I also did the same experiment by starting the Fluree server via https://github.com/fluree/server/blob/da13c507126b11ae3043a757f478777b7db929fe/dev/src/user.clj#L111

However, everytime I do the next step of the tutorial:

curl -H "Content-Type:application/json" --data "@resources/00_create_ledger.jsonld" localhost:58090/fluree/create

I receive the following error in the Fluree server log:

08:23:50.339 [qtp709276713-38] DEBUG fluree.server.components.http - Unwrapped credential with did: nil

Initially, I tried to do the tutorial directly on the documentation page. But there I received the following error:

Hi @maxweber - thanks for opening an issue for this. Looks like the syntax has not yet been updated for the latest release of Fluree v3. I'll get that updated now so this tutorial will work for you.

That said, there is a known issue with browser-based Fluree so the documentation page that may continue to be broken.

Jackamus29 commented 8 months ago

Hi again @maxweber - please pull the latest commit and try the walkthrough in the README again. Let me know how it goes!

maxweber commented 8 months ago

Hi @Jackamus29 awesome :partying_face: Now every step of the tutorial works :+1: Thanks a lot.
