GetFileSystemContent@1

Node GetFileSystemContent@1 reads the binary content of a System.Reporting/FileSystemItem back into the pipeline as a base64 string. It is the read counterpart of CreateFileSystemUpdate@1 and enables pipelines that process previously stored files asynchronously — for example a polling analysis pipeline that picks up staged uploads for OCR and AI extraction.

transformations:
  - type: GetFileSystemContent@1
    rtIdPath: $.key.Attributes.FileRtId # JSON path to the RtId of the FileSystemItem to read
    targetPath: $.pdf.data # The base64-encoded file content is stored here
    fileNameTargetPath: $.pdf.fileName # Optional output path for the stored file name
    contentTypeTargetPath: $.pdf.contentType # Optional output path for the stored content type
    contentLengthTargetPath: $.pdf.length # Optional output path for the content length in bytes

Configuration Parameters

Parameter	Type	Required	Default	Description
rtIdPath	string	Yes	-	JSON path to the RtId of the System.Reporting/FileSystemItem whose content should be read
fileNameTargetPath	string	No	-	Output path for the stored file name
contentTypeTargetPath	string	No	-	Output path for the stored content type
contentLengthTargetPath	string	No	-	Output path for the content length in bytes

Error Handling

• If the value at rtIdPath is not set, the node fails with a Value not set error
• If no FileSystemItem with the given RtId exists, the node fails with Entity with RtId '…' not found
• If the item has no stored binary content, the node fails with File system item '…' has no binary content

Example: Asynchronous document analysis

A staging pipeline stores uploads via CreateFileSystemUpdate@1 and records the file's RtId on a staging entity. A second pipeline (polling trigger) loads the content back and processes it:

  - type: FromPolling@1
    interval: 00:05:00
