Problem with citing

[pascalhuszar]

Hey, i want to add this reference https://dl.acm.org/doi/book/10.5555/517162 into my thesis and cite it. But after i added and cite, the warrning 'undefinde' occur.
Here is the bib:

@book{10.5555/517162,
author = {Langer, Hagen},
title = {Parsing-Experimente},
year = {2001},
isbn = {3631371950},
publisher = {P. Lang Publishing Co.},
address = {USA}
}

Any suggestions? Except that, every bib works

Could you add how you cite in the latex file? What's the exact error message? What environment are you using and have you compiled twice to allow for the compiler to allocate the space required for citations?

I fixed the problem: i rerun biber over main-english.tex
Thanks anyway :)

@pascalhuszar You can also use latexmk, which is an advanced make automatically checking which latex tools should be run.
