Deadline VersionQuery fails with poor error message

[ddneilson]

When using the VersionQuery construct to query for a version of Deadline that does not exist, then the error message that you get does not clearly indicate what the problem is.

Reproduction Steps

Either VersionQuery with a non-existent Deadline version (ex: 10.1.99), or

1. In the RFDK repository, modify scripts/getSupportedDeadlineVersion.ts to add versionString: "10.1.99" to the props of the call to getVersionUris
2. From the jsii/superchain docker container in the root directory of the RFDK repo, run: node ./scripts/getSupportedDeadlineVersions.ts

Error Log

When using the VersionQuery:

Failed to create resource. Cannot convert undefined or null to object
