Unable to save - error message

Hi,
This is my first time using Jabref.
I created a library with 2020 references but when I try to save the library I get the following error message:

“Could not save file…
Error in field ‘abstract’: Unescaped ‘}’ character without opening bracket ends string prematurely.”

Can anyone help?

Many thanks!

Hi,

although the error message sounds a bit obscure, it’s indicating that you have an extra }-brace somewhere in your abstract in one entry without ab opening bracket {. This creates invalid bibtex.
I hope you saved a bit more often, so maybe it’s just the last added entry.
You could try to open the file in an advanced text editor (e.g. Notepad++ on windows) that highlights matching braces and check manually if you spot it.
