Here is the error i got.
GelDB version 7.0-dev.9399+e5e6e72

I am trying to insert array of tuples.

part of schema: pairs: array<tuple<pair_id: int32, quote_idx: int32, quote_ca: str, quote_token: str, is_canonical: bool>>;

Error inserting token K: Error(

Here is the part of request i believe casing this error:

rust
pub struct L1ContractPairs(pub Option<Vec<(i32,i32,String,String,bool)>>);
impl Into<Value> for L1ContractPairs {
    fn into(self) -> Value {
        if let Some(pairs) = self.0 {
            let vec = pairs.into_iter().map(|p| {
                Value::Tuple (vec![
                        Value::Int32(p.0),
                        Value::Int32(p.1),
                        Value::Str(p.2),
                        Value::Str(p.3),
                        Value::Bool(p.4)
                ])
            }).collect::<Vec<_>>();

            Value::Array(vec)
        } else {
            Value::Nothing
        }
    }
}

Could you post a full program that reproduces this? I don't have enough to go on here.

(Though my first suspicion is a bug in the rust bindings, which is quite a bit less well tested than the server's encoding paths. Not certain, though.)
