Go Error: time.Time does not implement driver.Valuer (missing method Value)

Question

I'm working on a Go project where I'm using sqlboiler to generate code from a SQLite3 database that I created with a setup.sh script. I'm encountering an error that I can't seem to resolve. The error message is:

graph/db/repositories.go:998:23: cannot use o.CreatedAt (variable of type string) as driver.Valuer value in argument to queries.MustTime: string does not implement driver.Valuer (missing method Value)
graph/db/repositories.go:999:23: cannot use &o.CreatedAt (value of type *string) as sql.Scanner value in argument to queries.SetScanner: *string does not implement sql.Scanner (missing method Scan)

This error occurs when I try to use a time.Time value in my graph/db/repositories.go file. I'm using the golang:1.21-alpine3.18 Docker image for my project.

I've tried changing the created_at column type in the repositories table in my SQLite3 database. I've tested it with both TEXT and TIMESTAMP data types, but the error still persists.

Does anyone know what could be causing this error and how I can resolve it?

repositories.go

func (o *Repository) Insert(ctx context.Context, exec boil.ContextExecutor, columns boil.Columns) error {
    if o == nil {
        return errors.New("db: no repositories provided for insertion")
    }

    var err error
    if !boil.TimestampsAreSkipped(ctx) {
        currTime := time.Now().In(boil.GetLocation())

        if queries.MustTime(o.CreatedAt).IsZero() {
            queries.SetScanner(&o.CreatedAt, currTime)
        }
    }

    if err := o.doBeforeInsertHooks(ctx, exec); err != nil {
        return err
    }

    nzDefaults := queries.NonZeroDefaultSet(repositoryColumnsWithDefault, o)

    key := makeCacheKey(columns, nzDefaults)
    repositoryInsertCacheMut.RLock()
    cache, cached := repositoryInsertCache[key]
    repositoryInsertCacheMut.RUnlock()

It worked well. I changed the type of 'created_at' in the repositories of setup.sh to DATETIME and regenerated it. Thank you for your assistance below.

CREATE TABLE IF NOT EXISTS repositories(\
    id TEXT PRIMARY KEY NOT NULL,\
    owner TEXT NOT NULL,\
    name TEXT NOT NULL,\
    created_at DATETIME NOT NULL DEFAULT (DATETIME('now','localtime')),\
    FOREIGN KEY (owner) REFERENCES users(id)\
);
