Deploying a contract in the testing environment - functions not showing up and unable to continue

Hi, I am a buyer of the book (2nd edition) and I'm doing the tutorial in the book. I am at "Deploying a contract in the testing environment" and I'm stuck at point 5.

Here's my environment:

OS: Ubuntu 20.04.2 LTS ("focal") - running in VirtualBox on a Mac OS X Big Sur
VS Code: 1.58.2
Node: 10.19.0
NPM: 6.14.4
TypeScript: 4.3.5
IBP Extension: 2.0.4 (also tried 2.0.2, 2.0.0 and 1.0.40)

Here's my steps before I get stuck:

a. I cloned this repository and I open in VS Code the v1/trade folder. The book does not specify v1 but after packaging the contract screenshots and text specify "[email protected]" while the v2/trade folder would generate a "[email protected]".
b. I "disable the access control mechanism" by commenting out the contents of the beforeTransaction function in trade-contract.ts as shown in the book.
c. Next I connect to "1 Org Local Fabric" environment which I created from a template early in the book.
d. Although not in the book I do an "npm install" in a terminal window in the v1/trade directory - else the next step fails - this might need to be added in the book
e. In IBP extension, in the Smart Contracts section/"window" I "choose" command Package Open Project. This succeeds. After some log entries I get a "[email protected]" item in this "window".
f. Now I reach section "Deploying a contract in a testing environment". I select "Deploy smart contract" in Fabric Environments under "mychannel". A wizard appears and I'm on step 1.
g. From the "Choose a smart contract to deploy" I select "[email protected]" and click next just as the book says.
h. In the second step I have Definition name prefilled to "trade" and Definition version prefilled to "1.0.0" and I leave "Endorsement policy" as the book says. I click next.
i. In step 3 I only review previous steps' values and click deploy. I get a lot of log output (you can inspect at https://blog.andrei.rinea.ro/hlf01.txt). The screen looks like this:

j. In "Fabric Gateways" I click on "Org1 Gateway" as the book implies.
k. Although the book specifies that I should be asked for an identity, the VS Code IBP extension assumes "Org1 Admin" and populates the tree this way:

I expand "mychannel":

Finally I expand "[email protected]" node, or so I thought, but nothing appears underneath it:

Here's the log generated precisely when I tried to expand the "[email protected]" node: https://blog.andrei.rinea.ro/hlf02.txt

At this point I'm stuck and cannot continue as I don't get to the functions to be able to invoke them. I retried this using several versions of the IBP extension (2.0.4, 2.0.2, 2.0.0 and 1.0.40) with the same results. I even tried the v2/trade folder with the same results. What can be done?

Thanks,
Andrei Rinea.

Invoking and debugging a contract - Error

Hi, I'm at point 1 of "Invoking and debugging a contract" in chapter 5 of the second edition of the book. I'm using Ubuntu 20.04 desktop with:
Visual Studio Code
Version: 1.55.0
Commit: c185983a683d14c396952dd432459097bc7f757f
Date: 2021-03-30T16:02:21.560Z

Node.js: 12.18.3
V8: 8.7.220.31-electron.0
OS: Linux x64 5.8.0-48-generic snap

IBM Blockchain Platform v2.0.2

All works fine so far but when I try to submit a transaction using the requestTrade method I get this error:

ERROR] Error submitting transaction: No valid responses from any peers. Errors:
peer=org1peer-api.127-0-0-1.nip.io:8080, status=500, message=error in simulation: transaction returned with failure: Error: GET_STATE failed: transaction ID: 92e44da6063a8ca291740870303d14a516a5d6cc1f478041f9b19ec8d9bc3d6a: invalid key. Empty string is not supported as a key by couchdb

Any suggestions?

Unable o invoke functions of the contract "trade"

I am working through the chapter 5 Designing Smart Contract Transactions and Ledger Data Structures|Deploying a contract in the testing environment. I got stuck on step 5 which should allow to see the functions to be invoked. For some reason when I connected to the Fabric Gateway in VS Code it did not bring in the drop down menu for '[email protected]' under the Fabric Gateway section.

I'mreceiving an error that says it could not get the metadata for smart contract trade contract
