The solution involves using synchronous JS queries and ensuring that queries have completely finished before running the next query. The issue seemed to occur when a JS object returned with queries that hadn't completely finished, causing the next query to hang for about five minutes. The number of async queries may not be the issue.
The code example provided shows the parse_data function using await statements to run queries, followed by synchronous JS queries for processing data. The data is then inserted into the database using more asynchronous queries. The solution also includes exporting the JSON file for the team to investigate further.
