Error using createClient in Sanity and Typescript code

46 replies

Last updated: Mar 6, 2023

Hello All... new to Sanity and Typescript so there is probably an obvious answer, but I'm getting this error: TypeError: Object(...) is not a function using this codeimport { createClient } from '

user E

/client'import type { ClientConfig } from '

user E

/client';
export async function *getIgnoredHandles*() {
const config:
ClientConfig = { projectId: 'project id',
dataset: 'production',
useCdn: false,
// set to
true
to fetch from edge cache apiVersion: '2023-03-03',
// use current date (YYYY-MM-DD) to target the latest API version }

const client = *createClient*(config);
const response = await client.*fetch*('*[_type == "ignoredHandles"]');

const ignoredHandles: *IgnoredHandle*[] = response.*map*((handle: any) => ({
id: handle.id,
handle: handle.handle,
datereview: handle.datereview
}));

return ignoredHandles;

}

export interface
IgnoredHandle { id: string;
handle: string;
datereview: string;
}

Greetings! Does the error also give you a line number?

Thanks! Do you know what version of the

@sanity/client

package you’re using?

Mar 3, 2023, 11:29 PM

let me check

Mar 3, 2023, 11:29 PM

"@sanity/client": "^5.2.2", "@sanity/core": "^2.35.6",

Mar 3, 2023, 11:29 PM

and my tsconfig.json:{
"compilerOptions": {
"types": [
"@sanity/client"
],
"target": "es2017",
"lib": [
"dom",
"dom.iterable",
"esnext"
],
"allowJs": true,
"skipLibCheck": true,
"strict": true,
"forceConsistentCasingInFileNames": true,
"noEmit": true,
"esModuleInterop": true,
"module": "esnext",
"moduleResolution": "node",
"resolveJsonModule": true,
"isolatedModules": true,
"jsx": "react-jsx",
"incremental": true,
"allowSyntheticDefaultImports": true,
"noFallthroughCasesInSwitch": true
},
"include": [
"src",
"**/*.ts",
"**/*.tsx"
],
"exclude": [
"node_modules"
]
}

Can you check that you’re getting a response by console logging before you map over it?

Mar 3, 2023, 11:32 PM

yep

Mar 3, 2023, 11:32 PM

give me one min

Mar 3, 2023, 11:32 PM

I'm definitely not getting a response... it doesn't get that far

Mar 3, 2023, 11:35 PM

Got it, so the error happens as it’s being evaluated?

Mar 3, 2023, 11:37 PM

Yes, if I understand what you're saying... the project compiles, and then when I go to the page that calls the function getIgnoredHandles, I get the error

Mar 3, 2023, 11:38 PM

Nothing stands out to me as wrong with your code. Maybe try commenting it out, then reenabling line by line?

Mar 3, 2023, 11:46 PM

okay, I'll give it a shot

Mar 3, 2023, 11:46 PM

Does this make more sense? 44.chunk.js:22 Uncaught (in promise) ReferenceError: Cannot access 'createClient' before initialization

Mar 3, 2023, 11:51 PM

user M

Mar 3, 2023, 11:53 PM

Hmm, strange. You’re pretty clearly initializing the client before you make that call.

Mar 3, 2023, 11:54 PM

yeah, that's what I was thinking

Mar 3, 2023, 11:54 PM

I am sure it's something simple I'm doing wrong

Mar 3, 2023, 11:54 PM

I initially got the code from this page:
https://www.sanity.io/docs/js-client#get-client-configuration

Mar 3, 2023, 11:55 PM

in TypeScript section

Mar 3, 2023, 11:55 PM

I only have one real difference ... this is what's in the doc:

import {createClient, type ClientConfig} from '@sanity/client'

Mar 3, 2023, 11:56 PM

but when I use that, I get an error with the "type" reserved word

Mar 3, 2023, 11:56 PM

what version of Typescript should I be using?

Mar 3, 2023, 11:56 PM

I'm using "typescript": "^4.9.5",

Mar 3, 2023, 11:57 PM

Do you happen to be doing this inside of a V3 Studio?

Mar 3, 2023, 11:59 PM

no, it's a separate application and I'm just trying to pull information from sanity.io

Mar 3, 2023, 11:59 PM

Hi Lauren. Was this ever working for you in the past (i.e., on different versions)?

Mar 4, 2023, 12:00 AM

no... this is the first time I'm trying to do it

Mar 4, 2023, 12:00 AM

Would you mind trying v4 of

@sanity/client

Mar 4, 2023, 12:00 AM

sure... i didn't know there was one

Mar 4, 2023, 12:01 AM

how do I downgrade?

Mar 4, 2023, 12:01 AM

v5

@sanity/client

no longer supports ES5, and so I’m curious if that might be the issue when working with a Studio on v2.

Mar 4, 2023, 12:01 AM

in other words, what version do I need to target

Mar 4, 2023, 12:01 AM

is the studio part the @sanity/core?

Mar 4, 2023, 12:02 AM

You can delete your node_modules and lock file (presumably yarn.lock, on a v2 studio), then edit package.json and change the

@sanity/client

dependency to something like:

"@sanity/client": "^4",

. You would then run

yarn

Mar 4, 2023, 12:03 AM

Yes,

@sanity/core

is one of a few different “parts” that were central to a v2 studio. One of the big changes in v3 was going away from that parts system.

Mar 4, 2023, 12:04 AM

"@sanity/core": "^2.35.6",

Mar 4, 2023, 12:04 AM

what I'd really like to do is upgrade everything to the latest

Mar 4, 2023, 12:05 AM

That’s certainly the preferred approach, so that’s good to hear. There’s a migration guide as well as this community to help you along.

Mar 4, 2023, 12:06 AM

great!!

Mar 4, 2023, 12:06 AM

I didn't realize I wasn't on the latest

Mar 4, 2023, 12:07 AM

No problem!
