HelainSchoonjans opened a new issue, #14397:
URL: https://github.com/apache/grails-core/issues/14397
I have a Grails 3.3.2 application with GORM 6.1.8 and am using the mongodDB
grails plugin 6.1.4.
When trying to connect to a 3.4 MongoDB instance, the application makes an
error at startup:
> Caused by: com.mongodb.MongoCommandException: Command failed with error
67: 'Values in v:2 index key pattern cannot be of type bool. Only numbers > 0,
numbers < 0, and strings are allowed.' on server localhost:27017. The full
response is { "ok" : 0.0, "errmsg" : "Values in v:2 index key pattern cannot be
of type bool. Only numbers > 0, numbers < 0, and strings are allowed.", "code"
: 67, "codeName" : "CannotCreateIndex" }
Using the debugger, I could find the domain whose index creation failed:
class MyClass{
Long field1
String field2
Long index
static mapWith = "mongo"
static mapping = {
database "databasename"
}
static constraints = {
field1 nullable: true
field2 nullable: true
}
}
It embedded in another domain.
What's wrong with this domain class? I had the same results with a Mongo 3.6
and 4.0 instance ( I'm using the official mongoDB docker instances ).
PS: finally found it; the index attribute of the domain causes the error;
removing it makes everything work again.
