yaegi: import "go.uber.org/zap" fails

The following program sample.go triggers an unexpected result

package main

import (
	"time"

	"go.uber.org/zap"
)

func main() {
	logger, _ := zap.NewProduction()
	// defer logger.Sync() // flushes buffer, if any
	sugar := logger.Sugar()
	sugar.Infow("failed to fetch URL",
		// Structured context as loosely typed key-value pairs.
		"url", "blabla",
		"attempt", 3,
		"backoff", time.Second,
	)
	sugar.Infof("Failed to fetch URL: %s", "blabla")
}

Expected result

{"level":"info","ts":1625585709.656375,"caller":"yaegi/foo.go:15","msg":"failed to fetch URL","url":"blabla","attempt":3,"backoff":1}
{"level":"info","ts":1625585709.656471,"caller":"yaegi/foo.go:21","msg":"Failed to fetch URL: blabla"}
