由于无法读取日志文件，任务失败 [英] Task fails due to not being able to read log file
问题描述
Composer 由于无法读取日志文件而导致任务失败，它抱怨编码不正确.
Composer is failing a task due to it not being able to read a log file, it's complaining about incorrect encoding.
这是出现在用户界面中的日志:
Here's the log that appears in the UI:
*** Unable to read remote log from gs://bucket/logs/campaign_exceptions_0_0_1/merge_campaign_exceptions/2019-08-03T10:00:00+00:00/1.log
*** 'ascii' codec can't decode byte 0xc2 in position 6986: ordinal not in range(128)

我尝试在谷歌云控制台中查看该文件，但它也抛出了一个错误:
I try viewing the file in the google cloud console and it also throws an error:
Failed to load
Tracking Number: 8075820889980640204
但我可以通过 gsutil 下载文件.
But I am able to download the file via gsutil.
当我查看文件时，它似乎有文本覆盖其他文本.
When I view the file, it seems to have text overriding other text.
我无法显示整个文件，但它看起来像这样:
I can't show the entire file but it looks like this:

@-@{} 片段似乎位于典型日志的顶部".
Where the @-@{} pieces seems to be "on top of" the typical log.
推荐答案
我遇到了同样的问题.就我而言，问题是我删除了用于检索日志的 google_gcloud_default 连接.
I faced the same problem. In my case the problem was that I removed the google_gcloud_default connection that was being used to retrieve the logs.
检查配置并查找连接名称.
Check the configuration and look for the connection name.
[core]
remote_log_conn_id = google_cloud_default
然后检查用于该连接名称的凭据是否具有访问 GCS 存储桶的正确权限.
Then check the credentials used for that connection name has the right permissions to access the GCS bucket.
