Bitcoin: RPC bulk call suddenly stops working

I have this code that was working less than a week ago. No changes were made to my computer or code and it suddenly stopped working.
Normal (single) RPC calls work fine, but batch calls do not.
All transactions are rejected with an error message and I cannot recover them. It is as if the bulk call is no longer responding.
I have tried restarting my system, updating my client software, and checking for problems with my local network, but nothing seems to work. I also checked the Bitcoin RPC (Remote Procedure Call) service documentation and found that it only supports single RPC calls, not batches.
This is causing a problem for anyone using the Bitcoin protocol, as batch transactions are becoming more popular in the community.
What is causing the problem?
The exact cause of this error is currently unknown. I have tried searching online for possible solutions or fixes, but nothing has worked so far.
It is possible that there has been a new update or change to the Bitcoin protocol that affects batch transactions, or perhaps there is some other technical issue, whatever the reason, it is clear that this is a frustrating issue for anyone who relies on batch transactions.
What can I do?
If you are experiencing similar issues with batch transactions, I recommend contacting the Bitcoin community forums or mailing lists for advice and assistance. You may also consider reporting the issue to the developers of your chosen cryptocurrency client software, as they may be able to provide a fix or update.
In the meantime, it is important to be careful when using batch transactions, as they can pose risks if not managed properly. Be sure to thoroughly test any new code or changes before implementing them in a production environment.
Update:
As of my last check, I am not aware of any recent patch or update that addresses this issue. Users are advised to be vigilant and be on the lookout for future updates or changes that may affect batch transactions.
Stay safe online!
