getting autonaming config: %w

Error message

getting autonaming config: %w

What it means

`pulumi up` parses the project's autonaming configuration (autonaming patterns/overrides scoped to the stack) into an autonamer before running the deployment. This error wraps a failure of autonaming.ParseAutonamingConfig, meaning the autonaming settings in the project or stack config could not be parsed or decrypted.

Solutions

1. Review the `autonaming` section in Pulumi.yaml for syntax errors and fix the pattern
2. Inspect the wrapped inner error (%w) to identify the bad value or key
3. If autonaming overrides use secrets, verify PULUMI_CONFIG_PASSPHRASE / secrets provider
4. Remove or simplify the autonaming config temporarily to isolate the problem

Example fix

// before
# Pulumi.yaml
autonaming:
  pattern: "${name}-{{...invalid...}}"
// after
autonaming:
  pattern: "${config::project}-${name}"

// Ensure Pulumi.yaml autonaming block parses as valid YAML before up
import fs from 'fs';
import YAML from 'yaml';
const proj = YAML.parse(fs.readFileSync('Pulumi.yaml', 'utf8'));
if (proj.autonaming && typeof proj.autonaming !== 'object') {
  throw new Error('autonaming section malformed');
}

function hasValidAutonaming(proj) {
  return !proj.autonaming ||
    (typeof proj.autonaming === 'object' && typeof proj.autonaming.pattern === 'string');
}

try {
  execSync('pulumi up', { stdio: 'inherit' });
} catch (e) {
  if (String(e.message).includes('getting autonaming config')) {
    console.error('Check the autonaming section of Pulumi.yaml:', e.message);
  }
  throw e;
}

When it happens

Trigger: Running `pulumi up` when autonaming config in Pulumi.yaml (or stack config overrides) has an invalid pattern, malformed value, or a secret value that the decrypter cannot decrypt.

Common situations: Miswritten autonaming pattern syntax in Pulumi.yaml, autonaming override keys in stack config that don't parse, or encrypted autonaming values with a wrong passphrase/secret provider.
