## Pin your `fastapi` version { #pin-your-fastapi-version }

The first thing you should do is to "pin" the version of **FastAPI** you are using to the specific latest version that you know works correctly for your application.

For example, let's say you are using version `0.112.0` in your app.

func (where Where) Build(builder Builder) {
	if len(where.Exprs) == 1 {
		if andCondition, ok := where.Exprs[0].(AndConditions); ok {
			where.Exprs = andCondition.Exprs
		}
	}

	// Switch position if the first query expression is a single Or condition
	for idx, expr := range where.Exprs {
		if v, ok := expr.(OrConditions); !ok || len(v.Exprs) > 1 {
			if idx != 0 {
				where.Exprs[0], where.Exprs[idx] = where.Exprs[idx], where.Exprs[0]

 * <p><b>Important:</b> although the first interpretation resembles how most multimaps are
 * <i>implemented</i>, the design of the {@code Multimap} API is based on the <i>second</i> form.
 * So, using the multimap shown above as an example, the {@link #size} is {@code 3}, not {@code 2},
 * and the {@link #values} collection is {@code [1, 2, 3]}, not {@code [[1, 2], [3]]}. For those

	ast1, err := parser.ParseFile(fset, name, src, flags)
	if err != nil {
		if list, ok := err.(scanner.ErrorList); ok {
			// If err is a scanner.ErrorList, its String will print just
			// the first error and then (+n more errors).
			// Instead, turn it into a new Error that will return
			// details for all the errors.
			for _, e := range list {
				fmt.Fprintln(os.Stderr, e)
			}
			os.Exit(2)
		}
