Expected Resource or Concept in hyperledger-composer playground - hyperledger-composer

Question

I have an error said "Expected Resource or Concept" in playground hyperledger-composer
Two participants
1. School
2. Company
Two assets
1. Transcript
2. Transcript_status
One transaction updateStatus:
• Update student’s transcript status from unread to either not interested or interested
Participant school, student, company
Assets Transcript, Transcript_status
Transaction updateStatus
School creates a participant school
Company creates a participant company
School creates an asset transcript
Company creates an asset transcript_status
Workflow: After creating student’s asset (transcript), schools can upload the record to its website, and companies can view the first asset Transcript. After that, companies can submit transaction Transcript_status and marked as read. Then the asset Transcript_status will be updated from unread to read.

Answer 1

As per my understanding, I run your code. I had fix some issues. In your code, you may update a readStatus under a transcript asset. If you update a single value under s asset so you need to put an object of that asset in the Update function.
1. Model File Changes:
transaction UpdateTranscript_status {
o Boolean readStatus default=false
--> Transcript transcript
}
2. logic.js Changes:
async function transcriptForUpdated(TforUpdated) {
// eslint-disable-line no-unused-vars
TforUpdated.readStatus = true;
TforUpdated.transcript.readStatus = TforUpdated.readStatus;
const registry = await getAssetRegistry('org.school.education.Transcript');
await registry.update(TforUpdated.transcript);
}
After Running this transaction it will update a readStatus (false value update by true) under a Transcript asset.
Hope it will fix your issue :)
