Encountering a 400 error in a custom N8N workflow with Qdrant integration. Need guidance on configuring collections and workflow settings. Revised sample process below:
{
"workflowName": "TestPipeline",
"nodes": [
{
"id": "nodeX",
"name": "EmbedModule",
"type": "custom-embed",
"config": {}
},
{
"id": "nodeY",
"name": "VectorHandler",
"type": "custom-vector",
"config": { "collection": "docsSample" }
}
]
}
In my experience with similar setups, the issue often comes down to subtle misconfigurations. I encountered a comparable 400 error during my N8N and Qdrant integration because the collection details did not match between the modules and Qdrant itself. I found that ensuring the schema in Qdrant was correctly defined before referencing it in N8N made a huge difference. Debugging the intermediate payloads helped me pinpoint configuration mismatches. Revisiting the official documentation on both tools also provided clarity on the proper workflow settings, which resolved the error for me.
Based on my experience with similar integrations, I encountered a situation where a mismatch between N8N workflow configurations and the collection settings in Qdrant caused a similar error. The issue was resolved by ensuring that both systems had aligned definitions for fields and indexes. Reviewing the configuration details in both N8N and Qdrant, even small discrepancies can disrupt the process. Testing incremental adjustments allowed me to pinpoint the exact misconfiguration, reiterating the importance of precise parameter replication between the tools.
hey dancingfox, i’ve seen similar 400 errors before. sometimes it comes down to minor naming mismatches between n8n and qdrant. try verifying your collection name is an exact match and check for any plugin updates.
When I encountered a similar 400 error during my integration work with n8n and Qdrant, I found that the troubleshooting process required a thorough review of both the workflow configurations and the data schema in Qdrant. In my case, the issue was not only with the collection name match but also with subtle discrepancies in how data fields were defined. I carefully verified that the data structure in n8n exactly matched the schema expected by Qdrant. I also refreshed my modules to ensure compatibility with the latest API changes. This methodical approach helped resolve the error and ensured smoother processing thereafter.
