ES JsonParseException

Foobar_Geez · September 18, 2014, 1:25am

Hello,
I am a newbie to ES and would appreciate any insights into the below issue
(going crazy for the last couple of hours :/):

I need to store the following string value into a field -- foo\bar -- with
the literal backslash in it.

curl -XPUT 'http://localhost:9200/test/test/test' -d '
{
"rules": [
{
"users" : [ "foo\bar" ]
]
}'

I get the following error:

{"error":"RemoteTransportException[[High-Tech][inet[/X.X.X.X:9300]][index]];
nested: MapperParsingException[failed to parse [rules.users]]; nested:
JsonParseException[Unrecognized character escape 'k' (code 107)\n at
[Source: UNKNOWN; line: 10, column: 42]]; ","status":400}

I tried "foo\bar" and the value gets stored as "foo\bar".

Any ideas on how to store "foo\bar" with the literal backslash in it?

Thanks in advance!

Hello ,

This don't have to do anything with the escape character -
Try below -

curl -XPUT 'http://localhost:9200/test/test/test' -d '
{
"rules": [
{
"users" : [ "foo\bar" ]
}
]
}'

Thanks

Thanks. I provided a bad example as I guess I over-simplified it and also
edited it to remove proprietary data (thus, missed }).

The following example exhibits the same issue as described in my original
post.

curl -XPUT 'http://localhost:9200/test/test/test' -d '
{
"rules": [
{
"users" : [ "mile\kilo" ]
}
]
}'
{"error":"RemoteTransportException[[High-Tech][inet[/X.X.X.X:9300]][index]];
nested: MapperParsingException[failed to parse [rules.users]]; nested:
JsonParseException[Unrecognized character escape 'k' (code 107)\n at
[Source: UNKNOWN; line: 5, column: 40]]; ","status":400}

As with many other languages, literal backslashes in string literals
need to be written \.

curl -XPUT 'http://localhost:9200/test/test/test' -d '
{
"rules": [
{
"users" : [ "mile\kilo" ]
}
]
}'
