Is it possible to use service bindings with `vectorize` db?

I have a worker A that uses worker B. This worker B has bindings to a

vectorize

vectorize

vectorize

vectorize index (this index works when used by itself).
Both are deployed (given that vectorize doesn't work locally) , but this fail with

Cannot read properties of undefined (reading 'VECTORIZE')

Cannot read properties of undefined (reading 'VECTORIZE')

Cannot read properties of undefined (reading 'VECTORIZE')

Cannot read properties of undefined (reading 'VECTORIZE'), which is the binding defined in
the

wrangler.toml

wrangler.toml

for

WorkerB

WorkerB

WorkerB

WorkerB. I guess i'm missing something obvious or this cannot work. (the deployed url from the worker A fails with

Error 1101

Error 1101

Error 1101

Error 1101)

That won't work like you expect - you can access env from entrypoints with this.envthis.env

    async getSimilarImages() {
        return this.env.VECTORIZE.queryById('FJ4188-100_0_0_crop_1_res');
    }

    async getSimilarImages() {
        return this.env.VECTORIZE.queryById('FJ4188-100_0_0_crop_1_res');
    }
