Hi, while recording call with egress, i am getting the below error;

{"nodeID": "NE_covsMANvq7zS", "clusterID": "", "egressID": "EG_KUNk68CGLVWk"}
2025-12-12T08:44:25.864Z        DEBUG   egress.psrpc.IOInfo.UpdateEgress        rpc/logging.go:68       client response {"nodeID": "NE_covsMANvq7zS", "clusterID": "", "topic": [], "request": {"egressId": "EG_KUNk68CGLVWk", "roomId": "RM_iB7nwopspUDs", "roomName": "call-1765529046", "sourceType": "EGRESS_SOURCE_TYPE_WEB", "status": "EGRESS_ABORTED", "startedAt": 1765529050386979932, "endedAt": 1765529065858947790, "updatedAt": 1765529065858947790, "details": "End reason: Source closed", "error": "Start signal not received", "errorCode": 412, "roomComposite": {"roomName": "call-1765529046", "audioOnly": true, "audioMixing": "DEFAULT_MIXING", "preset": "H264_720P_30", "fileOutputs": [{"fileType": "OGG", "filepath": "/2025-12-12/call-1765529046", "s3": {"accessKey": "<redacted>", "secret": "<redacted>", "sessionToken": "<redacted>", "assumeRoleArn": "<redacted>", "region": "us-east-1", "bucket": "livekit_bucket", "forcePathStyle": true}}]}, "file": {"filename": "/2025-12-12/call-1765529046.ogg", "startedAt": 1765529065814486336, "endedAt": 1765529065814486336}, "fileResults": [{"filename": "/2025-12-12/call-1765529046.ogg", "startedAt": 1765529065814486336, "endedAt": 1765529065814486336}]}, "response": {}, "duration": "2.673872ms"}

my egress is running on ec2, whereas the dispatch call is taking places via a service on eks. i am using the below approach for recording the conversation:

req = api.RoomCompositeEgressRequest(
                room_name=room_name,
                audio_only=True,
                file_outputs=[
                    api.EncodedFileOutput(
                        file_type=api.EncodedFileType.OGG,
                        filepath=file_path,
                        s3=api.S3Upload(
                            bucket=self.s3_bucket,
                            region=self.s3_region,
                            force_path_style=True
                        )
                    )
                ]
            )

# Start recording
await ctx.api.egress.start_room_composite_egress(req)

and below is the egress logs:

and anyone tell me what could be the possible root cause?

are you using custom recording template? (https://docs.livekit.io/home/egress/custom-template)

no, i just want to record the ongoing call via egress, the setup was working fine when everything was on ec2 but since we separated out, we are facing the issue

the recording doesn't start because for some reason we don't get START_RECORDING signal from the template..

hey @boundless-author-7811 can u share how did u setup a self hosted server on aws currently i am having issues doing so
