Missing "Invoker\InvokerInterface" after fresh install – Not documented dependency?

[chr1st0ph9]

Hi everyone,

I’ve recently installed the latest version of EspoCRM on a clean Debian 12 server reimporting my previous 8.x espocrm config. Everything went well, but I keep getting the following error in the logs, when a mail message is received:

[2025-04-20 20:19:03] ERROR: EmailAccount 575ae4d5c0a791845, import message; 0 Interface "Invoker\InvokerInterface" not found

It seems to be related to a missing PHP dependency – specifically the php-di/invoker package, which provides the Invoker\InvokerInterface interface.
I tried to find similar reportings on the forum without success, if someone has an idea, I would happy to know it :-)

best Regards,
Christophe

Hello ,
finally, I got it to work but I just copied the contents of the data folder and imported the previous database.
Happy Easter
