Suddenly getting frequent failures with Vision product_search

[hardcorerobot]

The majority of my calls now return:

error {
code: 13
message: "Internal error."
}

which I can't find any information about. If I retry enough it will work as usual. Is there something happening server side? Anyone else affected?

Using Python 3.9 with google-cloud-vision 3.7.4 and it started within the last 2 weeks.
