Moonbeam demo cannot work with required Turing version

[morkeltry]

Moonbeam demo pre-requisite is given as

Turing Network v2.0.0

however, sendExtrinsicPromise in common.js contains no scheduleAs parameter.

Result:

b). Send extrinsic from moonbase-local to turing-local to schedule task. Listen to TaskScheduled event on turing-local chain ...
Listen XCMP task events
Error: The scheduleAs parameter should not be empty
    at Object.scheduleXcmpTimeTaskWithPayThroughRemoteDerivativeAccountFlow (..../node_modules/@oak-network/src/index.ts:244:15)
    at scheduleTask (..../src/moonbeam/common.js:200:11)
    at main (..../src/moonbeam/moonbase-local.js:45:3)

scheduleAs parameter is apparently no longer required in v.2.1.4 but I could not verify whether the demo works with that version due to

Apparently wrong version downloads from releases v.2.14

Let’s make sure the instructions of Moonbeam demo in README.md is up-to-date too.

Hi @morkeltry,

We have re-tested the xcm-demo and made some changes in #114. Please take a look at the new instructions, give it another try, and let us know how it goes!

The xcm-demo code was updated to use OAK-blockchain v2.1.4, but instructions in README.md weren’t. This PR is to update the README.md to make sure release versions match the code.

Thank you for your feedback 👍
