additional spaces are missed in the JSON output

[oleksandrborniak]

Bug Description

n8n does not output multiple spaces in JSON output.

To Reproduce

Environment: Doker, Image docker.n8n.io/n8nio/n8n:latest (1.53.2)

Create an Edit Fields node with the following content: "Department": "VZ - PHL - Head Office - G&A"

Or copy-paste this node: { "meta": { "instanceId": "f6951f98b505224e8a04a3bb7be358db57756dc7b87fabf383dcd7473ecd987f" }, "nodes": [ { "parameters": { "assignments": { "assignments": [ { "id": "e2252351-b410-462f-8a69-3ba4cbd5e201", "name": "Department", "value": "VZ - PHL - Head Office - G&A", "type": "string" } ] }, "options": {} }, "id": "cc562aaa-1ae5-4669-bdae-a3bff37944fb", "name": "Edit Fields", "type": "n8n-nodes-base.set", "typeVersion": 3.4, "position": [ 880, 120 ] } ], "connections": {}, "pinData": {} }

Execute Node and switch on the JSON tab. Try to find "VZ - PHL - Head Office - G&A"

You can notice that the JSON value is different: JSON value: "VZ - PHL - Head Office - G&A" Original value: "VZ - PHL - Head Office - G&A"

The original value has two spaces after "Office" and two spaces before "G&A" JSON value has one space after "Office" and one space before "G&A"

Test workflow: TMP.json

Expected behavior

JSON does not miss additional spaces.

Hey @oleksandrborniak,

We have created an internal ticket to look into this which we will be tracking as "GHC-161"

[oleksandrborniak]

Thank you.

Hey @Joffcom, I'm just checking in to see if you've had a chance to reproduce the issue and confirm whether it's a bug.

Hey @oleksandrborniak,

I have just taken a look and on the latest 1.55.3 release this doesn't appear to be an issue.

Can you try updating and see if you have the same problem.

[oleksandrborniak]

The result is the same. Just compare visually the two values and let me know if you see a difference.

Firefox:

Chrome:

I expect to see something like this:

I can see the exact difference in spaces in this example ^

Hey @oleksandrborniak

Looking at it in the JSON view it looks like one space but if I search for VZ - PHL - Head Office - G&A it is showing the correct value, If I click on the pencil icon to edit the data as well I can also see the 2 spaces are there.

Looking at this again I have just realised the issue is not with the functionality it is just that the space characters are not clearly displayed.

I will get this moved to the correct team to fix in a future version.

Great. Thanks.
