UNEXPECTED_INTERNAL_API_ERROR occurs when a remaketing list contains > 400 rules , created by API

[Jian Xu]

Hi, 

I've met an InternalApiError.UNEXPECTED_INTERNAL_API_ERROR, when i use the Adwords API to create a remarketing list which contains a list of String rules (the relation between the rules is OR).  The test is done with an test account.

After multi tests, i've found that if the rules is less then 400, it could pass. Otherwise , adwords will always return an internal error. 

Below is the soap msg , with 464 StringRuleItems:

Do you have any idea about that? Thanks!

Find a solution, we could use logicalUserList to separate these rules.
