SDK list blockchain with pageSize parameter Issue - Error Code 400

HI,
I use
Fireblocks Sandbox env and
com.fireblocks.sdk:fireblocks-sdk:14.0.0

I try to call
com.fireblocks.sdk.api.BlockchainsAssetsApi.listAssets

it works by passing null to all parameters to this method:
listAssets(
null,
null,
null,
null,
null,
null,
null,
null,
null
);
and I can get my 73 listed Assets

But when I try with pagesize = 10 like

listAssets(
null,
null,
null,
null,
null,
null,
null,
BigDecimal.TEN,
null
);

I get
java.util.concurrent.CompletionException: graphql.CodedException: Execution error: com.fireblocks.sdk.ApiException: listAssets call failed with: 400 - {“message”:“Bad Request Exception”,“code”:0}

Can you explain ? Did someone already have this issue?

Thanks
Fabien
