Access to storage is not allowed from this context.

Trying to use storage.get() in a content script results in Access to storage is not allowed from this context.
Here's my code:

// content.ts

const storage = new Storage({ area: "session" })

const init = async () => {
  value = await storage.get("key")
}

init()

I can't call storage.get() outside an async function so am I doing something wrong?

The session area is relatively new (introduced in Chrome 102). I suspect some unique property of session-type storage causes this.

From the docs

By default, it's not exposed to content scripts, but this behavior can be changed by setting chrome.storage.session.setAccessLevel().

setAccessLevel isn't supported in Plasmo so you need to call it from the browser storage api.

// background.ts

(async () => {
  const storage = new Storage({ area: "session" })
  const extStorageApi = storage.getExtStorageApi()
  await extStorageApi.session.setAccessLevel({ accessLevel: "TRUSTED_AND_UNTRUSTED_CONTEXTS" })
})()
