[Mandiant] Connector does not show accurate progess, and ingests reports very slowly

[damians-filigran]

Description

When ingesting reports, for the first day's ingest, the connector shows 100% progress, but then continues to ingest and increase the total operations despite the job apparently being completed. This continues for 1hr so far, with the count going higher and higher, despite the job showing as complete.

Environment

1. OS: SaaS
2. OpenCTI version: 6.2.8
3. OpenCTI client: Edge on MacOS
4. Other environment details:

Reproducible Steps

Steps to create the smallest reproducible scenario:

1. Configure Mandiant connector
2. Set start date from 2 months ago
3. Click into connector status view
4. Watch the completed job continue to build total count

Expected Output

Job should stay as In Progress until complete

Actual Output

Job apparently complete

Job even more complete

Additional information

In effect, this accompanies a very slow ingest of the report from the API, maybe 1 operation per second, for Reports specifically.
