Sting to object

[Shehram_Baig]

I have to send data to an api, which excepts a single object but n8n always outputs a array what to do here? how can I have output just in {} and not in [{}]?

(Select the nodes {
  "nodes": [
    {
      "parameters": {
        "mode": "runOnceForEachItem",
        "jsCode": "// In \"Run Once for Each Item\" mode, use $input.item.json\nconst data = $input.item.json;\n\nreturn {\n  sourceTypeId: Number(data.sourceTypeId),\n  filingUrl: data.filingUrl,\n  documentType: data.documentType,\n  originalID: data.originalID,\n  commentOriginal: data.commentOriginal,\n  tbcStyle: data.tbcStyle,\n  tbcMessage: data.tbcMessage,\n  botgate_s3Uri: data.botgate_s3Uri,\n  n8n_workflowId: data.n8n_workflowId,\n  n8n_executionId: data.n8n_executionId,\n  n8n_executionStep: Number(data.n8n_executionStep),\n  transmissionType: data.transmissionType,\n  filingMapped: data.filingMapped || null,\n  rawData: {\n    filingProperties: {\n      issuerName: data.rawData?.issuerName || null,\n      publishingDateOriginal: data.rawData?.publishingDateOriginal || null,\n      sourceNote: data.rawData?.sourceNote || null\n    },\n    transactionProperties: data.transactionProperties || []\n  }\n};"

Hi @Shehram_Baig

You can use the set node with a field type object:

@mohamed3nan Hi mohamed, thanks for reply thing is I cant seem to get rid off this [ ] wrapper making it an arrary, can you please take a look the output should be just a single object { } that I can call in http request node’s json body. thanks!

[mohamed3nan]

@Shehram_Baig

that I can call in http request node’s json body

in the http JSON body write this expression:

{{ $json.object_name.toJsonString() }}
