Cant assign task to user.

Hello, im having an issue when Im tryin to assigned a task in Hubspot with a user:
Im doing the following request:

async function createHubspotTask(createdHubspot, taskTitle, taskBody, userId) {

const url = “https://api.hubapi.com/crm/v3/objects/tasks”;

const now = new Date();

const timestamp = now.toISOString();

const data = {

properties: {

  hs\_timestamp: timestamp,

  hs\_task\_subject: taskTitle,

  hs\_task\_body: taskBody,

  hs\_task\_type: "TODO",

  hs\_task\_status: "NOT\_STARTED",

  hubspot\_owner\_id: userId,

},

};

const config = {

headers: {

  Authorization: \`Bearer ${createdHubspot.accessToken}\`,

  "Content-Type": "application/json",

},

};

try {

const res = await axios.post(url, data, config);

return res.data;

} catch (error) {

console.error("Error creando la task de hubspot: ", error);

}

}
The errror im having is:
Property values were not valid: [{“isValid”:false,“message”:“50481782 was not a valid owner ID”,“error”:“INVALID_OWNER_ID”,“name”:“hubspot_owner_id”,“localizedErrorMessage”:"50481782 was not a valid owner ID.

But I think the user ID its Ok, because is the same that it appears on my profile user url:
https://app.hubspot.com/settings/24325849/users/user/50481782, as you can see my id is 50481782 so IDK why im receiving that error from the API.
Someone knows if Im missing something?
Thank you

My bad, I was using the suerId instead of ownerId.
