New Star from ZTF Photometry produces HTTP error code 400

Hi
When I try to use the “New Star from ZTF Photometry” for the star ZTF18abcxlta, I get a persistent response of “Server returned HTTP response code: 400 for URL: https://irsa.ipac.caltech.edu/cgi-bin/ZTF/nph_light_curves?FORMAT=TSV&POS=CIRCLE%20345.08691%2056.03399%200.00040&BAD_CATFLAGS_MASK=65535”.

This has been going on for several days, but the exact same query has worked in the past.

I am on version 2.25.0 of VStar.

Hi Paul

Long time no key.

When entering the URL generated by the ZTF plugin (see Copy to Clipboard button) into a web browser:

https://irsa.ipac.caltech.edu/cgi-bin/ZTF/nph_light_curves?FORMAT=TSV&POS=CIRCLE%20345.08691%2056.03399%200.00040&BAD_CATFLAGS_MASK=65535

I see this error embedded in the VOTable response:

UsageFault: Internal error (invalid TAP query)

This may be due to an API change but I’m unsure right now. I have logged this as a GitHub issue:

I note however that selecting and entering an Object ID works for this object, 1837102100018050 in this case. Can you confirm? See the help document for the plugin or ask for clarification here if needed.
