It looks like your topic is missing some important information. Could you provide the following if applicable.

  • n8n version:
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:

@code_werich , you left a lot for a guess. It would help if you could provide the actual setup of your HTTP Request node.

Though, the error is clear, your payload is not a valid JSON. My guess that your are using JSON body. Try to replace your payload with expression like this.

    "issues": [
    "data": {
      "fields": {
        "summary": $json.summary,
        "description": $json.description
      "releaseVersion": "5.3.2"

If still doesn’t help, please, share the whole HTTP Request node and the values of that $json item.
