Troubleshooting

Start from the observed symptom, reproduce it with the smallest entrypoint, and inspect the layer that owns that behavior. Phalcon Kit uses the same configured services across HTTP, CLI, and WebSocket modes, but each process can still load a different environment or PHP configuration.

First Five Checks

Run these before changing application code:

php --version
php -r 'echo phpversion("phalcon") ?: "phalcon not loaded", PHP_EOL;'
composer check-platform-reqs
composer validate --strict --no-check-publish
git status --short

Then confirm the process has the expected environment:

php --ini
php -r 'var_export([getcwd(), getenv("APP_ENV"), getenv("DATABASE_HOST")]);'

Never print passwords, tokens, private keys, or full environment dumps into CI logs or public issues.

Application Does Not Boot

Class ... not found

Check in this order:

  1. The namespace matches the file path and Composer PSR-4 mapping.
  2. composer dump-autoload completes.
  3. The app loader registers the application namespace before bootstrap.
  4. A renamed Zemit class is not still referenced.
  5. The failing process uses the current deployed vendor directory.
composer dump-autoload -o
rg 'Zemit\\|zemit-cms' app config public cli websocket

A provider fails during bootstrap

Providers must define a non-empty service name and receive a PhalconKit\Di\DiInterface container. Inspect the provider configured as the key and implementation value:

'providers' => [
    \PhalconKit\Provider\Identity\ServiceProvider::class =>
        \App\Provider\Identity\ServiceProvider::class,
],

If a custom bootstrap supplies its own DI, use PhalconKit\Di\Di, PhalconKit\Di\FactoryDefault, or PhalconKit\Di\FactoryDefault\Cli rather than a native-only container.

A Service Is Missing Or Has The Wrong Type

Confirm three things:

  1. The provider appears in app config.
  2. The provider registers the same stable service name callers use.
  3. The resolved object implements the contract expected by the caller.

Use typed resolution at composition boundaries:

$logger = $di->getTyped('logger', \Phalcon\Contracts\Logger\Logger::class);

Avoid fixing a type mismatch with an unchecked cast or by widening every consumer to mixed. The service definition or provider override is usually the real ownership point.

Routes Return 404 Or The Wrong Action

Check the complete route-to-dispatch path:

  • the web server points to public/;
  • unknown files are forwarded to public/index.php;
  • the expected module is registered and selected;
  • controller namespaces match the module configuration;
  • action names follow the route convention;
  • permission failures are not being mistaken for route misses.

For REST resources, remember that route action keys are dash-case—such as find-with or archive-project—while PHP methods are camelCase, such as findWithAction() and archiveProjectAction().

curl --include http://127.0.0.1:8000/api/project

Inspect the status, response envelope, and debug output in a development environment. Do not enable detailed exception output in production.

Database Or Migration Failures

The app connects to the wrong database

Compare the environment seen by the exact process that fails. CLI migrations and PHP-FPM may load different .env files or working directories.

Verify host, database, username, port, and adapter without printing the password. Then run the project’s migration list command before applying anything.

Generated models do not match the schema

The scaffolder reads the live database, not the migration source files. Confirm the migration ran against the intended database, then regenerate and inspect the diff:

./bin/migration-list.sh
./bin/migration-run.sh
./vendor/bin/phalcon-kit cli scaffold run --src-dir=app/ --namespace=App
git diff -- app/Models

Do not hand-edit generated abstract models to hide drift. Correct the migration or scaffolding configuration and regenerate.

REST Requests Behave Unexpectedly

A field cannot be saved, filtered, or exposed

REST capabilities are allowlisted separately. Check the controller initializer for the exact operation:

  • initializeSaveFields()
  • initializeFilterFields()
  • initializeSearchFields()
  • initializeExposeFields()
  • initializeWith()
  • initializeDistinctActionFields()

A field being safe to expose does not automatically make it safe to save or filter.

A relationship causes many queries

Use findWith()/findFirstWith() for a server-selected graph or the native eager parameter where appropriate. Confirm the relationship alias in the generated model and do not request the same graph through both mechanisms.

Counts differ from list length

Pagination, grouping, joins, and embedded count policy can intentionally make these values differ. Distinguish:

  • page length;
  • normal count;
  • grouped bucket count;
  • bucketTotal;
  • ungrouped totalCount.

Read REST APIs before changing count SQL in an application controller.

Permission Problems

Separate feature policy from row policy:

  • feature/role policy decides whether an action is available;
  • permission conditions restrict which rows the query returns;
  • behavior overrides modify query behavior for a specific feature or role.

When debugging, record the controller, route action, normalized feature name, active roles, and symbolic permission-condition keys. Do not log JWTs, session IDs, password hashes, or personal record contents.

If super roles see data but normal users do not, inspect row-level conditions before adding broader feature grants.

HTTP Works But CLI Or WebSocket Fails

Compare:

which php
php --ini
php -m
pwd

Also compare the working directory, environment file, mounted secrets, and deployed release path. Long-lived workers must be restarted after code, configuration, or extension changes; PHP-FPM reloads do not restart a separate Swoole process.

Static Analysis And Runtime Disagree

The usual causes are:

  • IDE stubs do not match the loaded Phalcon extension;
  • the analyzer uses a different PHP version;
  • generated code is stale;
  • a test double exposes a broader or narrower signature than runtime;
  • caches contain results from a previous dependency graph.

Clear only tool-specific caches, then rerun the smallest failing command. Do not delete the lock file or vendor directory as a first diagnostic step.

Before Opening An Issue

Prepare a minimal, non-sensitive report:

  • expected and actual behavior;
  • smallest reproducing code or request;
  • PHP and Phalcon versions from the failing process;
  • installed Phalcon Kit package version;
  • database adapter when relevant;
  • exception class and sanitized stack trace;
  • whether the failure occurs in HTTP, CLI, WebSocket, or all modes;
  • checks already attempted.

Security vulnerabilities belong in the private process described by SECURITY.md, not a public issue.
