Create platform and can not connect ping

I created a new platform but when I cloned the source, I didn't see the lib/... folder, only env. Then I created a .env file and added those files, then pinged but got error 500. What should I do next?

here is the app

What's the SDK version?

it looks like 1.8.0

You're self-hosting?

no, but i can ask the host

@D5 yes, I self-hosting

Try asking the owner for the server logs

The react native SDK version or Appwrite version?

the Appwrite version, sdk-version: 17.0.2, and from the project : "appwrite": "^17.0.0", "expo": "~52.0.28", "react-native": "0.76.6",

I see the error on server log:

appwrite | [Error] Timestamp: 2025-09-24T15:05:47+00:00 appwrite | [Error] Method: GET appwrite | [Error] URL: /v1/ping appwrite | [Error] Type: Utopia\Database\Exception\Structure appwrite | [Error] Message: Invalid document structure: Unknown attribute: "pingCount" appwrite | [Error] File: /usr/src/code/vendor/utopia-php/database/src/Database/Database.php appwrite | [Error] Line: 4271

I checked on /usr/src/code/src/Appwrite/Utopia/Response/Model/Project.php docker and I see code have define pingCount, pingedAt

->addRule('pingCount', [
  'type' => self::TYPE_INTEGER,
  'description' => 'Number of times the ping was received for this project.',
  'default' => 0,
  'example' => 1,
])
->addRule('pingedAt', [
  'type' => self::TYPE_DATETIME,
  'description' => 'Last ping datetime in ISO 8601 format.',
  'default' => '',
  'example' => self::TYPE_DATETIME_EXAMPLE,
])

==> it means the response Model (Project.php) - Used for API responses ✅ Working (I think that)

I checked the database and tried update pingCount and I see that database work well

MariaDB [appwrite]> SELECT pingCount, pingedAt  FROM _console_projects  WHERE _uid = '682f5edd0032dee5xxx' LIMIT 1;
+-----------+----------+
| pingCount | pingedAt |
+-----------+----------+
|         0 | NULL     |
+-----------+----------+
1 row in set (0.001 sec)

MariaDB [appwrite]> UPDATE _console_projects SET pingCount = pingCount + 1, pingedAt = NOW(3) WHERE _uid = '682f5edd0032dee5xxx';
Query OK, 1 row affected (0.015 sec)
Rows matched: 1  Changed: 1  Warnings: 0

MariaDB [appwrite]> SELECT pingCount, pingedAt  FROM _console_projects  WHERE _uid = '682f5edd0032dee5xxx' LIMIT 1;
+-----------+-------------------------+
| pingCount | pingedAt                |

So I think root cause: Collection Schema (Structure validator) - Used for database validation ❌ Broken The Structure validator in Database.php line 4271 is checking against the collection schema

I have checked the cache and restarted Docker several times, but the issue has not been resolved. Do you have any suggestions? cc @D5

Did you ever figure this out? I had the same issue and was able to find a temporary workaround, but it's not pretty.
