JS SDK run_query causing an error

Looker Q&A Looker

Hello! I’m using the Looker JS SDK v4.0 inside an extension framework app. I’m trying to use the run_query method but it is failing. Here’s what I’m doing:

try {

const res = await core40SDK.ok(core40SDK.run_query(30731, "csv"));

console.log(res);

} catch (error) {

console.error(error);

}

And I’m getting the following error

TypeError: Cannot read property 'toString' of undefined at encodeParam (transport.js:115)

at methods.js:2772

at Generator.next (<anonymous>)

at asyncGeneratorStep (methods.js:1)

at _next (methods.js:3)

at methods.js:3

at new Promise (<anonymous>)

at methods.js:3

at Looker40SDK.run_query (methods.js:2787)

at EmbedLook.js:71

I already queried that queryId using Python and Looker API and I’m getting the correct data. I don’t know if I’m missing something. Here’s the docs link I’m using as a base https://docs.looker.com/reference/api-and-integration/api-reference/v3.1/query#run_query

Any help will be appreciated!
