Error installing Bibliography module

Has anyone else experienced the following error when installing the Bibliography module and know how it can be fixed?

Deprecated : Array and string offset access syntax with curly braces is deprecated in /var/www/html/omeka-s/modules/Bibliography/vendor/geissler/converter/library/bibtexParse/PARSEENTRIES.php on line 254

We’re using Bibliography version 3.3.1.6 on Omeka S 3.1.2, but we also had the same error using version 3.1.5.2 with Omeka S 3.0.2.

Many thanks,
Donna

The deprecation notices here are coming from a library used by the Bibliography module that doesn’t fully support PHP 8.0.

You’d probably want to bring this issue up to the developer of the Bibliography module.

These are just notices so they aren’t necessarily an immediate problem: with “development” mode turned off you wouldn’t see them and they wouldn’t affect anything. Still worth reporting, though.
