[BUG] UnexpectedException: SObjectType is not available in DescribeSObjectResult

[ppillai7777]

Ran the graph engine scan on our application source as shown below and report shows the InternalExecutionError rules.

sfdx scanner:run:dfa --format=csv --outfile=CodeAnalyzerDFA9.csv --target="./" --projectdir="./" --category="Security" --sfgejvmargs "-Xmx30g" --pathexplimit -1 --rule-thread-count 2 --rule-thread-timeout 21600000

Description column shows the following:
Graph Engine identified your source and sink, but you must manually verify that you have a sanitizer in this path. Then, add an engine directive to skip the path. Next, create a Github issue for the Code Analyzer team that includes the error and stack trace. After we fix this issue, check the Code Analyzer release notes for more info.
