We are running a Flink job using several operators including map, windowing, flatMap() and the job fails with the following error - just wondering what causes this error:

It seems that You are using keyBy operation and the extracted key is null. You can't really have null key in Flink.
I'm trying to create source connector for my SQL Server tables, here's an example:
{
"name": "test",
"config": {
"tasks.max":"1",
"connector.class": "io.confluent.connect.jdbc.JdbcSourceConnector",
"connection.url": "jdbc:sqlserver://REDACTED;databaseName=REDACTED",

"topic.prefix": "test",
"poll.interval.ms" : 2000,
"table.whitelist": "dbo.Client",
"mode":"incrementing",
"incrementing.column.name": "Id"
}
}
I'm getting following error, which doesn't say anything...
java.lang.IllegalArgumentException: Number of groups must be positive.

The same happens when I use mode timestamp with timestamp.column.name (column Modified with type datetimeoffset).
When I use mode bulk with a custom query, it works fine.
Any ideas?

I am using the Gmail API to create a label, using URL https://www.googleapis.com/gmail/v1/users/me/labels. Works perfectly for me. However several customers are reporting this fails with http error 400, with the error:
"domain": "global", "reason": "parseError", "message": "Parse Error"
The json that is input to the call is very simple, example:
{"name":"Secretarial Misc."}
Any idea what the problem could be? Why would the exact same json work for me but not somebody else?
The data you show should, according to the specification, not work for anyone. It's peculiar that is works for you! Try this:
POST https://www.googleapis.com/gmail/v1/users/me/labels?access_token={YOUR_API_KEY}
{
"labelListVisibility": "labelShow",
"messageListVisibility": "show",
"name": "Secretarial Misc."
}

Anyone seen it before?
Yeah, in my opinion, something is wrong with Cloud Endpoints in general. My working code from last week suddenly gives me these errors as well. It happened a few times before: google code
