Steps to reproduce

1. Open https://peaq.subscan.io/account/0x3a9A81d576d83FF21f26f325066054540720fC34?tab=contract
2. select "Solidity (Standard-JSON-Input)
3. Compiler version 0.8.9
4. Upload https://gist.github.com/jtakalai/44012fd56bf5a29b5975778b25a745e2 as the file
5. Hit Verify & Publish

Expected output

The contract verified

Actual output

Toast saying "Request failed with status code 499", or "Metadata file not found. Did you include \"metadata.json\"?" (with status 500)

Additional factoids or references

I've previously successfully validated a contract using the "Solidity (Single file)" option, but here it gave the same error. Also since this Standard-Input-JSON is direct from compiler to verified process with no manual tweaking (like flattening) in the middle, I decided to add it to the ticket.

@jtakalai I have checked you uploaded JSON input file. This JSON is not a standard JSON input. You can refer to this document https://docs.soliditylang.org/en/latest/using-the-compiler.html#input-description
