Path-problem result pattern

**Description of the issue**

Hello, I made a query that seems to be working just fine using the VS Code extension. However, when I try to query my database using the CLI with this query I am getting this error.

> A fatal error occurred: Could not process query metadata for C:\Users\Kyler\Documents\Work\cwe200\codeql\codeql-custom-queries-java\CWE-535\ExposureofInformationThroughShellErrorMessage copy.ql.
Error was: Expected result pattern(s) are not present for path-problem query: Expected at least two result patterns. These should include at least an 'edges' result set (see https://codeql.github.com/docs/writing-codeql-queries/creating-path-queries/). [INVALID_RESULT_PATTERNS]

I have read through that link and I have also checked out [this](https://github.com/github/codeql-cli-binaries/issues/115) issue here and did some looking into other path problem examples. However, I am still getting this error after trying all of this. I believe that it is something simple that I am missing right in front of me. Any help would be appreciated. Thank you in advance.

My code

}

from ShellErrorExposureConfig config, DataFlow::PathNode source, DataFlow::PathNode sink
where config.hasFlowPath(source, sink)
select sink, source, sink, "Potential CWE-535: Exposure of information through shell error message"
```
I tried updating my select statement to match the example in this code
`codeql\ql\java\ql\src\Security\CWE\CWE-532\SensitiveInfoLog.ql`

To be
```
select sink.getNode(), source, sink, "This $@ is written to a log file.", source.getNode(),
"potentially sensitive information"
```
