CDS List Records action randomly not returning all columns

Using List Records CDS action to get activitymimeattachments from D365 to post them to sharepoint.  These are pdf files generated from a report that get attached to emails.  Seems like there is a severe limitation in the size of fields returned by this action.

Need to get filename and body from the activitymimeattachment, however body is a base64 encoded binary file and when it gets large,, list records truncates the body field and all fields appearing after it like filename.

The record I get back looks like this:

"@odata.context": "$metadata#datasets('contoso.crm')/ta...",
"": "",
"@odata.etag": "",
"ItemInternalId": "9a8bc8d7-30d0-ea11-a812-000d3a8c954b",
"overwritetime": "1900-01-01",
"attachmentnumber": 0,
"solutionid": "25a01723-9f63-4449-a3e0-046cc23a2902",
"_objectid_value": "8d8bc8d7-30d0-ea11-a812-000d3a8c954b",
"_objectid_type": "emails",
"activitymimeattachmentidunique": "2b6e090b-caf7-4206-9e4c-1e736a81288a",
"isfollowed": false,
"activitymimeattachmentid": "9a8bc8d7-30d0-ea11-a812-000d3a8c954b",
"_attachmentid_value": "9b8bc8d7-30d0-ea11-a812-000d3a8c954b",
"_attachmentid_type": "attachments",
"ismanaged": false,
"objecttypecode": "email",
"componentstate": 0,
"_componentstate_label": "Published",
"versionnumber": 133001837,
"attachmentcontentid": null,
"anonymouslink": null


It does not contain the 2 fields I am interested in.

Any ideas?

Posting the in a web browser does return body and filename.


Hi @bwilliamson,


Which CDS connector are you using? Is the regular CDS or CDS (Current Environment)?
