Why Are Some Filename Values Missing When Converting JSON in PowerShell?

Asked By CuriousCoder123 On

Hey everyone! I'm working on a process where I'm converting JSON to a PowerShell object. I noticed that in some cases, a key-value pair, specifically 'filename', is showing up as blank after conversion. For instance, I'm using the command: `$json_converted = get-content $json | ConvertFrom-json | select -expandproperty vulnerabilities`. In one of the items, it shows 'filename' as blank, but in the original JSON source, it clearly has a value like 'spring-security-crypto-6.3.0.jar'. Interestingly, when I convert the same JSON to CSV, all filename entries are populated. Has anyone experienced this issue? Any thoughts on why some 'filename' values aren't coming through in the conversion process? By the way, I managed to solve the issue! It turned out that I had a mistake in my code with an '=' instead of '-eq' in an if statement, so that fixed everything and it's working fine now!

It sounds like a depth issue when you're running the conversion command. Sometimes, if the nested structure is too deep, PowerShell might skip over certain values. You might want to try adjusting the depth parameter in the `ConvertFrom-Json` command and see if that helps! Just keep in mind that it could impact how other items are retrieved too.

I hear you, but just changing the depth might not solve the issue completely. If all items in your library are structured the same, it baffles me why it would affect just the filename. I'd recommend double-checking the JSON for any inconsistencies or hidden characters that might disrupt the parsing.
