Panic reflect

[tpoxa]

I use protobuf generated struct as one of my model's field

type Element struct {
	bun.BaseModel `bun:"table:elements,alias:element"`
	ID            string                 `bun:"id,nullzero,notnull,pk"`
	FlowID        int                    `bun:"flow_id,nullzero,notnull,pk"`
	Revision      int                    `bun:"revision,nullzero,notnull,pk"`
	Component     string                 `bun:",nullzero"`
	Data          *platform.GraphElement `bun:",nullzero,notnull,type:jsonb"`
}

GraphElement consists of structured elements, which we use in some grpc responses as is.

During insert, I've caught the following panic message:

[bun]  23:00:02.390   ROLLBACK                  9µs  ROLLBACK     *errors.errorString: driver: bad connection

go version go1.19.4 darwin/arm64

Is this because of protoc-generated structs?
Thanks.

This is probabably fixed in v1.1.12

Indeed it is, thank you
