Hello, I’m trying to upload attachments from AGOL to AGOL using process described in the article How to Use the ArcGISAttachmentConnector, I’m on FME workbench 2026.1

On small test this runs fine, but when I start testing actual production feature services, I get error

The ArcGIS REST API returned an error: HTTP Error Code: 413 : '' Message Code . Further details: 'The page was not displayed because the request entity is too large

I have tried by lowering the number of records per request in the readers to 500 and 300 but it failed.

Is there a workaround for this? I do read all the records in; none are filtered (as I’m new to FME I stuck to the article). Would skipping the empty attachment records help? I feel it’s case where the mov files were attached that the upload failed, but I’m not 100% sure.

    Turns out the attachment type is not the issue, it’s the size. The flow fails every time it’s over 4Mb. To bypass this I have setup filters for this in order to download instances of bigger MOV files for analysis and the created an excel with corelating info on these.
