qryexe throws the error "Failed to find SQL table for type: String"

Hello.

I'm using Apache Ignite's REST API. While the qryfldexe command successfully executes SQL SELECT statements, the qryexe command does not perform as expected.

The POST body is:
`cmd=qryexe&keepBinary=true&type=String&pageSize=10&cacheName=MyCacheTable&arg1=1&qry=id%3D%3F`

It causes this error:
`Failed to find SQL table for type: String`

The saved data is like this:
```
{
"successStatus": 0,
"response": {
"items": [
[
1,
"XXXXXXXXXXXXXXXX",
1
]
],
"last": true,
"queryId": 209,
"fieldsMetadata": [
{
"schemaName": "PUBLIC",
"typeName": "MyCacheTable",
"fieldName": "ID",
"fieldTypeName": "java.lang.Integer"
},
{
"schemaName": "PUBLIC",
"typeName": "MyCacheTable",
"fieldName": "NAME",
"fieldTypeName": "java.lang.String"
},
{
"schemaName": "PUBLIC",
"typeName": "MyCacheTable",
"fieldName": "SCHEMA",
"fieldTypeName": "java.lang.Integer"
}
]
},
"sessionToken": null,
"securitySubjectId": null,
"error": null
}
```

I can't find any information in the documentation about how to address this issue.

It's an error? How can I make a qryexe request in the table MyCacheTable?

Thank you.

Start by reproducing the POST request for qryexe against MyCacheTable and compare its behavior with the working qryfldexe command. Review the qryexe and qryfldexe REST entry points and determine whether the request can query MyCacheTable without the reported "Failed to find SQL table for type: String" error.
