Cannot call upsertTransaction without not required paramter "schema"

[wmk1]

Currently there is attempt to create (or update) transaction using this endpoint:

https://developer.fiskaly.com/api/kassensichv/v1/#operation/upsertTransaction

However, I am always encountering an error regarding schema. I think that it's due to missing some properties upon V1Schema:

An error occured while attempting to connect with Fiskaly client. schema: Invalid type. Expected: object, given: string

so I am trying to make it without any schema as according to documentation, it's not mandatory parameter. Then, I am encountering another error:

An error occured while attempting to connect with Fiskaly client. The TSS is not initialized. ERROR (ErrorLogger.java:36:flush) {} - { Status: "400", Error: "Bad Request", Message: "The TSS is not initialized.", Code: "E_TSS_NOT_INITIALIZED", RequestId: "d97f07322cf51ef6a806df82888cbfc5"}

I am pretty sure that I am using valid TSS as I am using it during TSS initialization and Client ID initialization. My code snippet: public void finishTransaction(UUID tssId, UUID tssClientId, int lastRevision, V1StandardSchema schema) { UUID txId = randomUUID(); Map<String, Object> requestBody = new HashMap<>(); requestBody.put("state", ACTIVE); requestBody.put("client_id", Preconditions.checkNotNull(tssClientId)); //requestBody.put("schema", new Gson().toJson(schema)); Map<String, Object> queryParams = new HashMap<>(); queryParams.put("last_revision", lastRevision); try { tseClient.serveTransaction(tssId, tssClientId, txId, new Gson().toJson(requestBody), queryParams);

Issue closed, the bug was within code, not SDK itself.
