error make update ES request err The 1s id or PK value is nil, close sync

[kevisong]

Not sure why this is happening.
After sync to the point where the go-mysql-elasticsearch started. The following error pops out and the program exited.

I use id and uuid field to generate the es id field like below.

id = ["id", "uuid"]

Looks like the issue is caused by the "uuid" field.

Not sure why this field is causing this error.

This field has value that looks like this: 1596211247aad5020ad3z511ea81k88254008dd97a

Is it a string length problem? Can anybody help?

Update

I printed out the row which is used to get the ID. In sync.go line 449

It's all nil except for the id field.

Obviously the original data is not nil.

BTW, this happens when it syncs to the current time.

存量的可以同步，增量的无法同步。无法获取组合ID

Update

I made some changes in sync.go line 449. Instead of returning error. I return a default_key to make sure the process didn't crash.

Is it possible to merge this to the master branch? @siddontang
