Hi,

This error usually occurs when a transaction is waiting for a resource which is already locked by some other transaction.

First of all, after this error occurs, you should run SHOW ENGINE INNODB STATUS in order to get more information. Link: SHOW ENGINE INNODB STATUS[^]

Let me know the results.

Also, you should consider increasing the default (50 seconds) lock wait timeout value. Link: innodb_lock_wait_timeout[^]
