Error with superbase

[theceojose]

Hello,

I’m getting this error trying to create an AI agent to read a knowledge base.

{
“errorMessage”: “Your request is invalid or could not be processed by the service”,
“errorDescription”: “422 status code (no body)”,
“errorDetails”: {},
“n8nDetails”: {
“time”: “3/23/2025, 3:08:44 p.m.”,
“n8nVersion”: “1.83.2 (Self Hosted)”,
“binaryDataMode”: “default”,
“cause”: {
“status”: 422,
“headers”: {
“connection”: “keep-alive”,
“content-length”: “51674”,
“content-type”: “application/json”,
“date”: “Sun, 23 Mar 2025 19:08:43 GMT”,
“server”: “nginx”,
“strict-transport-security”: “max-age=63072000; includeSubDomains; preload”
},
“attemptNumber”: 3,
“retriesLeft”: 0
}
}
}

I imagine the error comes from the knowledge base in superbase output:

{
“type”:
“text”,
“text”:
“{“pageContent”:“This is where the big piece of crap is.”}”
},

Because it seems the JSON format is incorrect.

Do you know how I can fix this?

Hey, could you ctl a, ctl c on your entire workflow, and click the ‘</>’ button in the forums response and paste the workflow between the backticks that appear?

That would help give some more context on what is happening.

Where does this error occur, could you show a screenshot?

[theceojose]

It gives me this error

This is the output that the database gives me

I notice that they work with some agents, but not with others. And the database output remains the same.

Can you translate and provide the output here? Thanks.

@ThinkBot

ovide the output here?

What’s in another language is what’s in the knowledge base.

So it’s irrelevant.
