In-memory Vector Store Giving Error Message - Could not get parameter when using n8n 1.50.1

[jfang]

Describe the problem/error/question

When I tried to execute the workflow, I get the error message below in the In-Memory Vector Store1 sub-node. I’m getting the error message when I’m using the server with n8n 1.50.1. This is working fine for me on a local machine with n8n 1.48.3. Same nodes copied and pasted over. Is there a configuration I need to update that’s different from n8n 1.48.3?

What is the error message (if any)?

{
“errorMessage”: “Could not get parameter”,
“errorDetails”: {},
“n8nDetails”: {
“itemIndex”: 0,
“time”: “7/19/2024, 11:12:54 AM”,
“n8nVersion”: “1.50.1 (Self Hosted)”,
“binaryDataMode”: “default”,
“cause”: {
“level”: “error”,
“tags”: {},
“extra”: {
“parameterName”: “options”
}
}
}
}

Please share your workflow

I’ve shared the section within the red box below:

(Select the nodes on your canvas and use the keyboard shortcuts CMD+C/CTRL+C and CMD+V/CTRL+V to copy and paste the workflow.)

Share the output returned by the last node

Information on your n8n setup

• n8n version: 1.50.1
• Database (default: SQLite): SQLite
• n8n EXECUTIONS_PROCESS setting (default: own, main):
• Running n8n via (Docker, npm, n8n cloud, desktop app): Docker
• Operating system: Ubuntu 22.04 LTS

Hi @jfang

This seems to be related to your Q&A Chain Node “Create Summary and Tags”.
Can you share the error you are seeing there?

One thing you can try to do is to add a new Q&A Chain Node (updated version) and apply the same settings again. When copying over workflows new node version will not automatically be applied.

We have a pretty cool workflow template that checks for new node versions available to make sure your workflows are all kept up to date as well.

Check if workflows contain build-in nodes that are not of the latest version...

@ria Thanks for looking into this.

I’ve just tried again and got the same error message as I’ve noted in the original posting.

{
“errorMessage”: “Could not get parameter”,
“errorDetails”: {},
“n8nDetails”: {
“itemIndex”: 0,
“time”: “7/22/2024, 11:31:27 AM”,
“n8nVersion”: “1.50.1 (Self Hosted)”,
“binaryDataMode”: “default”,
“cause”: {
“level”: “error”,
“tags”: {},
“extra”: {
“parameterName”: “options”
}
}
}
}

This is using Question and Answer Chain node version 1.2.

I’ve now added a new Q&A Chain Node with the updated n8n version and applied the same settings and I am still getting the same error.

{
“errorMessage”: “Could not get parameter”,
“errorDetails”: {},
“n8nDetails”: {
“itemIndex”: 0,
“time”: “7/22/2024, 11:41:12 AM”,
“n8nVersion”: “1.50.1 (Self Hosted)”,
“binaryDataMode”: “default”,
“cause”: {
“level”: “error”,
“tags”: {},
“extra”: {
“parameterName”: “options”
}
}
}
}

This is using Question and Answer Chain node version 1.3.

Hey @jfang and @ria I also had the same problem with all newer version until 1.52.0.
I just downgraded my docker image to version 1.49.0 and the Q&A Chain Node is working again.

Do you guys know if there is any github issue open where I can track the resolution for this bug?

Thank you.

[miko]

same issue on 1.51.1

[netroy]

This was fixed here, and released in 1.52.0.

[miko]

was not fixed for me on 1.52.0

[netroy]

can you please share more details? like a screenshot, or the stacktrace from the UI?
I suspect you might be seeing another bug.

[jfang]

Thanks @netroy. It’s working for me again now in 1.52.2.
