Error with CryoSPARC live v4.6.2

Hi guys,
I was tring to use cryosparc live 4.6.2 to process images in real time. but it gives errors like this below. Does anyone have any idea what is going on?

Traceback (most recent call last):

@zcp Please can you post the output of the command

cryosparcm rtpcli "get_session_doc('P99', 'S9')['exposure_groups']"

(replacing P99, S9 with the actual project and session IDs of the problematic CryoSPARC Live session).

really appreciate your quick response. I run this command as you mentioned. it gives messages like this below

cryosparcm rtpcli "get_session_doc('P38', 'S2')['exposure_groups']"
[{'defect_path': None, 'exp_group_id': 1, 'file_engine_enable': True, 'file_engine_filter': '*.tif', 'file_engine_interval': 10, 'file_engine_min_file_size': 0, 'file_engine_min_modified_time_delta': 0, 'file_engine_recursive': False, 'file_engine_strategy': 'entity', 'file_engine_watch_path_abs': '/data/zcp/cryosparc-live/movie', 'final': True, 'gainref_path': '/data/zcp/cryosparc-live/movie', 'ignore_exposures': False, 'num_exposures_found': 1755, 'num_exposures_ready': 0}]

The Gain Reference Path parameter of the Exposure Group in the Live session’s configuration

currently seems to point to a directory, but should point to the absolute path of a compatible file, like
/data/zcp/cryosparc-live/movie/gain_file.mrc (if movies are not already gain-corrected).

Thanks. I sure this movies are gain-corrected. below is setting. I do not think the path for movies is not incorrect

what wtempel means is: the “directory to watch” can be a directory like /data/zcp/cryosparc-live/movie -but- the “gain reference path” must be filled out all the way to the exact single file ending in .mrc or .tif or similar like /data/zcp/cryosparc-live/movie/gain_file.mrc

what an amazing support team. really appreciate it. it works well after i tried as you mentioned(change gain path to /data/zcp/cryosparc-live/movie/gain.mrc ).
