# Troubleshooting

| Issue                     | Resolution                                                                                                                                                                                                                    |
| ------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Connector not in /v1/info | SPI file present under META-INF/services/ with the exact interface name and one fully qualified class name (FQCN) per line. Ensure the connector dependency is added to csp-api (and assembly). Rebuild CSP-API and assembly. |
| csp-sdk-core not found    | Build and install oe\_csp\_sdk\_core first (or publish it to the Maven repository used by your build). Ensure your Maven \`settings.xml\`/POM has access to the repository hosting \`csp-sdk-core\`                           |
| JDBC connection failure   | Ensure ConnectionConfig includes jdbcUrl and username/password. These must be set in the connector from attributes before calling ConnectionPoolManager. See MonetDB’s ensureConnectionConfig.                                |
| Assembly build failure    | Run mvn clean install from the root first so all connector modules are installed. Then run ./build-csp-sdk.sh or mvn clean install -pl assembly -am.                                                                          |
| Port already in use       | Change server.port in csp-api/src/main/resources/application.properties (default is 8800).                                                                                                                                    |
