[Bug Report] Persistent HTTP 500 Internal Server Error on Antigravity (Ultra Subscriber)

Google Antigravity
1

Hello Google AI Team,

I am currently a Google AI Ultra subscriber. Over the past few hours, I have been experiencing a persistent and repeated HTTP 500 Internal Server Error while trying to use Antigravity. This issue is completely blocking my workflow, and I am currently unable to utilize the service I am paying for.

Could you please investigate this server-side issue immediately? I would appreciate it if you could let me know if there is an ongoing outage or how this can be resolved.

Here is the error log for your reference (sensitive IDs have been partially masked):

Hi @Adnan_Khan1,

Welcome to the Forum,

Are you still seeing that Internal Server error? If so, which specific model were you calling when it failed?
