Error during upload of pre-aggregation: No such file or directory (os error 2)

I am using Pre-Aggregations with _CubeCore_ (@cubejs-client/core: "^0.33.12").
**FrontEnd**: Angular

**Problem**: I am getting an error when I run my code with pre-aggregation (_external: true_). Its working fine with (_external: false_)

**Error Message**:
> Error: Error during upload of dev_pre_aggregations.accounts_main_g4ftyje0_qybpynmr_1iaacui-0.csv.gz create table: CREATE TABLE dev_pre_aggregations.accounts_main_g4ftyje0_qybpynmr_1iaacui (`accounts__id` int, `accounts__name` varchar(255), `accounts__created_at_day` timestamp, `accounts__count` bigint): Internal: No such file or directory (os error 2)

My **Pre-Aggregation** looks like:

```
preAggregations: {
main: {
refresh_key: {
every: "10 seconds",
},
external: true,
measures: [accounts.count],
dimensions: [accounts.name, accounts.id],
timeDimension: accounts.created_at,
granularity: `day`,
},
}
```

**Complete Account Cube Code**:

```
cube(`accounts`, {
sql_table: `public.accounts`,
data_source: `default`,
joins: {
business_units: {
sql: `${CUBE}.business_unit_id = ${business_units}.id`,
relationship: `many_to_one`,
},
},
measures: {
count: {
type: `count`,
},
},
dimensions: {
id: {
sql: `id`,
type: `number`,
primary_key: true,
},
name: {
sql: `name`,
type: `string`,
},
created_at: {
sql: `created_at`,
type: `time`,
},
updated_at: {
sql: `updated_at`,
type: `time`,
},
},
preAggregations: {
main: {
refresh_key: {
every: "10 seconds",
},
external: true,
measures: [accounts.count],
dimensions: [accounts.name, accounts.id],
timeDimension: accounts.created_at,
granularity: `day`,
},
},
});
```

When I run my code. I am able to see that it is creating _csv.gz_ files in the _temp-uploads_ folder inside _CubeStore_. But after that I get the error 'No Such file or directory' which is mentioned above. _Uploads_ folder is empty.


I am stuck on this issue since quite a while. I tried to put this query on slack but have not got any reply, its been more than a week now. Posting it here hoping to get resolution of this problem.

Thanks for all the help.
