Description

I get this autocompletion error when using a biblatex+biber bibliography (exported by better bibtex for Zotero). It appears that the same error was an issue before (#1838) but there it occurred at a different place. It happens with both local and remote bibliographies.

Stacktrace

java.lang.IllegalArgumentException: Argument for @NotNull parameter 'element' of com/intellij/codeInsight/completion/BaseCompletionService$BaseCompletionResultSet.addElement must not be null
