Forge Storage API performance question

Hi, I use the Storage API when I save data in app development. And when I search the stored data, I call the Storage API in a for loop. (using async, wait)

But it seems to be unusually slow. It seems to take about 20 ~ 30 seconds. Therefore, time was shortened through parallel processing (using Promise.all), but the connect-src error occurs because it is too slow to fetch data. (In order to search the worklog, jira cloud api continues to get data with issue key in the for loop.)

Refused to connect to '' because it violates the following Content Security Policy directive: "connect-src 'self'".

Can you give me any advice on this?
