In this video we will walk you through:
00:00:00 Intro
00:03:51 What is conductor?
00:13:00 Play with Holochain CLI and Sandbox
00:28:32 Create DNA and hApp bundle
00:36:27 Install and run hApp in Conductor using Sandbox
00:45:17 creating a basic UI project step by step.
01:03:38 connect UI to hApp and call zome function
These sessions are mostly suitable for programmers and designers, so if you would like to participate you need to fill-out this application in advance.
Hi @hedayat i have tried to start the peershare happ. Should the current version in (GitHub - holochain-in-action/peer-share) work?
The sandbox gives me the following error when i press the button in the web UI.
[nix-shell:~/peer-share/holo-layer]$ hc s run -p=8900
Conductor ready.
hc-sandbox: Running conductor on admin port 40627
hc-sandbox: Attaching app port 8900
hc-sandbox: App port attached at 8900
hc-sandbox: Connected successfully to a running holochain

The webapp seems to run fine and i can open it in the browser:

Any clues that can direct me into the right direction?
Hi @wwo
I fixed the bug and pushed the changes to UI. Fetch project and re-run again.
The issue was about Payload. There was extra space in Payload TextBox so always there was an empty string sending to zome function while functions didnāt wait for any input parameter.
Thanks for testing and sharing.
Thank you for your answer. I just tried it now it works.
