Common Issues & Solutions

Issue 1: 404 Errors for Assets (Blank Screen After Deployment)

Symptoms:

• Deployed app shows blank screen
• Console shows: GET .../assets/index-xxx.js net::ERR_ABORTED 404
• MIME type error: Refused to apply style ... MIME type ('application/json')

Root Cause: Missing base: './' in vite.config.ts

Automated Fix:

// Check vite.config.ts
const config = await read('vite.config.ts');
if (!config.includes("base: './'")) {
  // Add base: './' to config
  const updated = config.replace(
    'export default defineConfig({',
    `export default defineConfig({\n  base: './',`
  );
  await write('vite.config.ts', updated);
  console.log('✅ Added base: "./" to vite.config.ts');

  // Rebuild
  await exec('npm run build');

  // Suggest redeploy
  console.log('💡 Run: pac code push');
}

Issue 2: System-Managed Field Error (Dataverse)

Symptoms:

• PrimitiveValue node with non-null value was found... 'ownerid'
• Create/update operations fail

Root Cause: Sending system-managed fields (ownerid, statecode, timestamps, primary key)

Fix: Review service layer and remove system-managed fields:

// ❌ WRONG
const payload = {
  name: dto.name,
  ownerid: '',  // Remove this
  statecode: 0, // Remove this
};

// ✅ CORRECT
const payload = {
  name: dto.name,
  // Dataverse sets ownerid, statecode automatically
};

Issue 3: Boolean Field Type Mismatch

Symptoms:

• Cannot convert the literal '1' to expected type 'Edm.Boolean'
• Update operations fail with Boolean fields

Root Cause: Generated types suggest numeric (0|1) but Dataverse expects boolean
