Arxiv BibTeX have no identifier in references

[hippke]

As noted by Jason Wright: When I export a BibTeX citation for an arxiv posting using ADS and put it into AASTeX, it shows up in my paper as "ArXiv e-prints" and has no proper identifier. Any way to fix this in 6.3?

Hi, thank you for this report. But it is insufficient to investigate as is. Can you please provide:

1. the bibtex you're using;
2. which bst file you are using;
3. the output .bbl entry for the given bibtex input.

Thank you.

For example, given aastex63.cls and aasjournal.bst the following bibtex

@ARTICLE{2019arXiv190210103B,
       author = {{Batygin}, Konstantin and {Adams}, Fred C. and {Brown}, Michael E. and
         {Becker}, Juliette C.},
        title = "{The Planet Nine Hypothesis}",
      journal = {arXiv e-prints},
     keywords = {Astrophysics - Earth and Planetary Astrophysics},
         year = "2019",
        month = "Feb",
          eid = {arXiv:1902.10103},
        pages = {arXiv:1902.10103},
archivePrefix = {arXiv},
       eprint = {1902.10103},
 primaryClass = {astro-ph.EP},
       adsurl = {https://ui.adsabs.harvard.edu/abs/2019arXiv190210103B},
      adsnote = {Provided by the SAO/NASA Astrophysics Data System}
}

produces this bbl

\bibitem[{{Batygin} {et~al.}(2019){Batygin}, {Adams}, {Brown}, \&
  {Becker}}]{2019arXiv190210103B}
{Batygin}, K., {Adams}, F.~C., {Brown}, M.~E., \& {Becker}, J.~C. 2019, arXiv

Thanks for checking and sorry for the bug report without example. I had used the modified .bst by @seawander from his update. The error is gone when I use the official bst file.
