Thank you for raising this issue. The extract container node is one of the more complex nodes in the project.
I appreciate you providing an image and example flow. This helps me significantly. I reviewed the tests for the container node and imported the example flow into my a test environment.
As it turns out, the error you are seeing is most likely from a misconfiguration and not an issue with the node itself. This project is perpetualy a work in progress. The issue you raised and the poor error message highlights the need for additional documentation for some of the more complex nodes.
The error shown in the image is thrown when the node can not find the Data API URL for the file it is supposed to extract. The most common cause for this is a misconfiguration of the node's container property. In the example, this property is configured in the inject node as fieldData.container.
@mw777eds Can you confirm that you have a URL in the payload.list.data array in the fieldData.container property? Here is a more concrete example:
Given the following input:
{
"data": [
{
"fieldData": {
"name": "Luke Skywalker",
"filename": "Luke-Skywalker.png",
"id": "38A5D5A7-473F-9F40-AF3B-6894B6D684C3",
"bio": "Discovered as a slave on Tatooine by Qui-Gon Jinn and Obi-Wan Kenobi, Anakin Skywalker had the potential to become one of the most powerful Jedi ever, and was believed by some to be the prophesied Chosen One who would bring balance to the Force. A hero of the Clone Wars, Anakin was caring and compassionate, but also had a fear of loss that would prove to be his downfall.",
"photo": "https://some-server.com/Streaming_SSL/MainDB/F483F8751E6891672E410D2A19850D980AC61DCDC4269ADDA38694496DE5292E.png?RCType=EmbeddedRCFileProcessor",
},
"recordId": "69622",
"modId": "2"
}
]
}I would configure the extract container node like this:
[
{
"id": "f3ef4b70.47d88",
"type": "dapi-container-data",
"z": "bf0e276f.55d598",
"name": "",
"parameters": "",
"parameterType": "none",
"data": "payload.data",
"dataType": "msg",
"field": "fieldData.photo",
"fieldType": "msg",
"filename": "fieldData.filename",
"filenameType": "msg",
"destination": "",
"destinationType": "buffer",
"output": "payload.files",
"x": 530,
"y": 60,
"wires": [
[
"33b3f243.e04af6"
]
]
}
]Please notice the values in the filename and field properties of the configuration object
I hope this helps you. Feel free to reopen this issue should continue to see an error.

Using your example for extract containers I get the following error: The 'url" argument must be of type string. Received type undefined.
