How to make JavaScript fetch request from a react app docker container to a Rails API docker container within the same network?

I have a couple of docker containers within a network. A container with a frontend react project and another container with a Rails API. I'm looking to make a request from the react project container to the Rails API but the fetch API continues to run into this error:

net::ERR_NAME_NOT_RESOLVED

React Code

function App() {

...
  async function apiRequest() {
    const options = {
      headers: myHeaders,
      method: requestMethod,
    }

    formData.append('username',username);
    formData.append('password',password);

    if (requestMethod === "POST") {
      options.body = formData
    }

    let requestStr = "http://user-api:3000/api/users/";
    let apiRequest = await fetch(requestStr, options)
    let data = await apiRequest.json()
    console.log(data)
  }
...
}

Dockerfile Frontend (React app using Vite)

FROM node
WORKDIR /app
COPY package.json .
RUN npm i
COPY . .
EXPOSE 5000
CMD ["npm", "run", "dev"]

Dockerfile Rails API

I've tried to place the rails API container name as the host within the fetch call but I haven't had any luck. Any advice?
