Introduction

When adding the OpenAI Connector module to a project, a compilation error occurs. The error message indicates that the symbol "properties()" cannot be found for the JsonNode type.

Environment

OpenAI Connector module (all versions)

Instructions/Procedure

The issue is caused by conflicting Java libraries. Specifically, old userlibs (from Mendix 9) are creating conflicts with newer vendorlibs of the same libraries. Since the older Jackson version does not contain the JsonNode.properties() method, the Java compilation fails. To resolve this issue, follow these steps:

• Make sure to take a backup of your project's userlib folder.
• Locate the Jackson JAR files in userlib folder.
• Remove these Jackson JAR files from the userlib folder.
• Run Clean Deployment Directory in Studio Pro.
• Run the application again.

Outcome

After removing the Jackson JAR files, Mendix will use its own bundled, compatible Jackson version, which should resolve the compilation error.
