Autocompleter doesn't work in TYPO3v9 (pageType without effect)

[AppWerft]

This code in Partials/Form/Fields/Text.html

{f:uri.action
         arguments:{dictionary:fieldInfo.autocompleteDictionary,q:'%%%%'},
         action:'suggest',
         pageType:'1369315139',
         additionalParams:{type:1369315139},
         format:'data',
         noCacheHash:1
 )}\"}

In the generated link the key type is missing. In older installation (8.*) it worked.
Here an example link:
https://hosdev.sub.uni-hamburg.de/de/suchen-entdecken/discovery/?tx_find_find%5Baction%5D=suggest&tx_find_find%5Bcontroller%5D=Search&tx_find_find%5Bformat%5D=data&tx_find_find%5Bq%5D=hamb&cHash=6c348fe79748ec6163d21aa39c563794

Any ideas? The added additionalParams: is a workaround, but didn't work.

If I use pageType:'1369315139', or additionalParams:{type:'1369315139'}, -- in both cases type=1369315139 isn't part of Uri.
If I use a test like additionalParams:{typex:'1369315139'}, then typexis part of query string. I think somebody removestype` from object.

Additional noCacheHash:1 doesn't work in v9.*.

OK, little progress:
If I add .data to the mapping in config.yaml file. In this case .data will appended to path with this result:

https://hosdev.sub.uni-hamburg.de/de/text-mit-suchschlitz.data?no_cache=1&tx_find_find%5Baction%5D=suggest&tx_find_find%5Bcontroller%5D=Search&tx_find_find%5Bformat%5D=data&tx_find_find%5Bq%5D=jena&cHash=08dfec0143f8f0d50be66a3271780472

This request generates an empty JSON array.

Degugging SolrServiceProvider.suggestQuery:

$arguments:

Array ( 
	[action] => suggest 
	[controller] => Search 
	[format] => data 
	[q] => jena 
) 

$this->query:

Solarium\QueryType\Suggester\Query Object
(
    [options:protected] => Array
        (
            [handler] => suggest
            [resultclass] => Solarium\QueryType\Suggester\Result\Result
            [dictionaryclass] => Solarium\QueryType\Suggester\Result\Dictionary
            [termclass] => Solarium\QueryType\Suggester\Result\Term
            [omitheader] => 1
            [build] => 
            [reload] => 
            [query] => jena
        )

    [helper:protected] => 
    [params:protected] => Array
        (
        )
)

$solrResults:

Array()

Search for jena works in solr console ;-)

How can I see the real http request against solr?

This is the $this->query in v8 of TYPO3:

Solarium\QueryType\Suggester\Query Object
(
    [options:protected] => Array
        (
            [handler] => suggest
            [resultclass] => Solarium\QueryType\Suggester\Result\Result
            [termclass] => Solarium\QueryType\Suggester\Result\Term
            [omitheader] => 1
            [query] => jena
        )
    [helper:protected] => 
    [params:protected] => Array
        (
        )
)

The main difference is the new [dictionaryclass] => Solarium\QueryType\Suggester\Result\Dictionary.

I guess an other default behaviour.

In current project we use TYPO3 v9 and solarium "~4.2"
In the older (running) project we use TYPO3 v8 and solarium "3.7"
The standard search request seems to work in both versions of solarium. The suggester makes trouble. Maybe we have to modify the suggestQuery-method.
