[Bug]: Only absolute URLs are supported

### What happened?

I am working on a project using [Meteor.js](https://www.meteor.com/) version 3.2.2. For those unfamiliar, Meteor.js is a Node.js framework. As stated in the title, I am getting the error **"Only absolute URLs are supported"** when trying to create a client. I am using an npm package and running Chrome in a Docker container, both of which are up-to-date. If I directly make an API request, there is no issue. To narrow down the problem, I added logs on the Node modules side. It also worked when I tried it directly on the node.
### Code inside the application:

```ts
Meteor.startup(async () => {
const tenantName = 'test';
const databaseName = 'test';

const client = new ChromaClient({
host: 'localhost',
port: 8000,
ssl: false,
tenant: tenantName,
database: databaseName,
fetchOptions: {
headers: {
Accept: 'application/json',
},
},
headers: {
Accept: 'application/json',
},
});
console.log(client);

const response = await client.version();
console.log(response);
});
```

### Log output from the package:

```js
var ChromaClient = class {
constructor(args = {}) {
let {
host = defaultChromaClientArgs.host,
port = defaultChromaClientArgs.port,
ssl = defaultChromaClientArgs.ssl,
tenant = defaultChromaClientArgs.tenant,
database = defaultChromaClientArgs.database,
headers = defaultChromaClientArgs.headers,
fetchOptions = defaultChromaClientArgs.fetchOptions
} = args;
if (args.path) {
console.warn(
"The 'path' argument is deprecated. Please use 'ssl', 'host', and 'port' instead"
);
const parsedPath = parseConnectionPath(args.path);
ssl = parsedPath.ssl;
host = parsedPath.host;
port = parsedPath.port;
}
if (args.auth) {
console.warn(
"The 'auth' argument is deprecated. Please use 'headers' instead"
);
if (!headers) {
headers = {};
}
if (!headers["x-chroma-token"] && args.auth.tokenHeaderType === "X_CHROMA_TOKEN" && args.auth.credentials) {
headers["x-chroma-token"] = args.auth.credentials;
}
}
const baseUrl = `${ssl ? "https" : "http"}://${host}:${port}`;
this._tenant = tenant || process.env.CHROMA_TENANT;
this._database = database || process.env.CHROMA_DATABASE;
const configOptions = {
...fetchOptions,
method: normalizeMethod(fetchOptions?.method),
baseUrl,
headers
};

Logger.info({ payload: configOptions }, "ChromaClient constructor configOptions");

const calculatedConfigOptions = w(configOptions);

Logger.info({ payload:calculatedConfigOptions }, "ChromaClient constructor calculatedConfigOptions");

this.apiClient = J(calculatedConfigOptions);

this.apiClient.setConfig({ fetch: chromaFetch });
}

//...
};
```

```js
var chromaFetch = async (input, init) => {
let response;
try {
response = await fetch(input, init);
} catch (err) {
Logger.info({ err, payload: { input, init } }, "chromaFetch error");
if (offlineError(err)) {
throw new ChromaConnectionError(
"Failed to connect to ChromaDB. Make sure your server is running and try again. If you are running from a browser, make sure that your ChromaDB instance is configured to allow requests from the current origin using the CHROMA_SERVER_CORS_ALLOW_ORIGINS environment variable."
);
}
throw new ChromaConnectionError("Failed to connect to Chroma");
}
if (response.ok) {
return response;
}
switch (response.status) {
case 400:
let status = "Bad Request";
try {
const responseBody = await response.json();
status = responseBody.message || status;
} catch {
}
throw new ChromaClientError(
`Bad request to ${input.url || "Chroma"} with status: ${status}`
);
case 401:
throw new ChromaUnauthorizedError(`Unauthorized`);
case 403:
throw new ChromaForbiddenError(
`You do not have permission to access the requested resource.`
);
case 404:
throw new ChromaNotFoundError(
`The requested resource could not be found`
);
case 409:
throw new ChromaUniqueError("The resource already exists");
case 422:
const body = await response.json();
if (body && body?.message.startsWith("Quota exceeded")) {
throw new ChromaQuotaExceededError(body?.message);
}
break;
}
throw new ChromaConnectionError(
`Unable to connect to the ChromaDB server. Please try again later.`
);
};
```
