Genesys_cloud_architect_flow export fails with schema validation error

My configuration keeps failing when attempting to bulk export Architect flows via the CX as Code CLI. The command genesys-cloud architect:flow:export-all executes but returns a 500 error for flows containing complex routing strategies.

“Export operations require the target directory to be writable and the API client to have Administrator privileges.”

$ genesys-cloud architect:flow:export-all --output ./flows
[INFO] Fetching flows...
[ERROR] Failed to export flow 'Main Inbound': Schema validation failed for 'initialContactUri'.

The spec defines initialContactUri as a string, yet the export process seems to be serializing internal references incorrectly. Is there a flag to force raw JSON export?
