Hey guys, I might be wrong, but there is an issue.
It was a hard bounce on order creation, Claude Code returned this as a root cause:
Title: EspoCRM upgrade broke Advanced Pack + tightened Formula validation → all record creates return HTTP 500
Environment: EspoCRM upgraded overnight, Advanced Pack installed, PHP 8, integrations posting via API.
Symptoms
All API POSTs (Opportunity, DeliveryOrder, workflow-triggered updates on Account/User/CCity) started returning HTTP 500 with a null body. Client-side you just see:
EspoCRM API request failed: | Endpoint: Opportunity | Method: POST | Response: null
Nothing useful in the API response — you have to check data/logs/espo-YYYY-MM-DD.log on the server.
Root cause 1 — Advanced Pack UpdateEntity
*******
Return type is declared bool, but metadata->get() returns null when the setting isn't defined on the entity → TypeError under PHP 8 → any workflow that touches an entity
without optimisticConcurrencyControl blows up.
Log signature:
ERROR: (0) Process ...: Espo\Modules\Advanced\Core\Workflow\Actions\Update Entity::hasVersionNumber(): Return value must be of type bool, null returned
BPM: triggerError
*****
Clear cache after (php command.php clear-cache).
