While updating to neos 4.0 I am running into this error message:
An exception occurred while executing ‘ALTER TABLE
flow_doctrine_migrationstatus CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci’:
Specified key was too long; max key length is 767 bytes
[ERROR] The transaction was rolled back.
Database charset/collation was converted.
Any idea how to fix that?
I assume you use MySQL/MariaDB?
You should probably use a more recent version then. MariaDB has to be 10.2 at least and you can check the requirements in the Neos documentation.
Thanks David for your fast answer!
Yes after upgrading to new Ubuntu 18 with Maria DB 10.2 this works without any problems.
