BRC20 endpoints unable to read array of string in query params

[ECBSJ]

i can't seem to get any results returned back from this BRC-20 API endpoint when passing in tickers as an array of strings:

curl example:
curl -X GET "https://api.hiro.so/ordinals/v1/brc-20/tokens?ticker=%5B%22piza%22%2C%22pepe%22%5D"

js fetch example:

const baseUrl = "https://api.hiro.so/ordinals/v1/brc-20/tokens"
const params = new URLSearchParams({
  ticker: ["piza", "pepe"]
})
const urlWithParams = `${baseUrl}?${params.toString()}`

let result = await fetch(urlWithParams, {
  method: "GET",
  headers: {
    "Content-Type": "application/json",
    Accept: "application/json"
  }
})

let response = await result.json()
console.log(response)

response:
{"limit":20,"offset":0,"total":0,"results":[]}
