Update a transaction: querystring.last_revision should be integer about fiskaly-kassensichv-client-java

I found the problem
transactionResponseMap.get("last_revision") returns NULL

I just added "?last_revision=1" (or what ever revision you have) without using the httpBuilder. So maybe you try httpBuider.build()+"?last_revision="+((String) transactionResponseMap.get("last_revision"))

Thank you for your response @cjaentsch Is it working for you?

I tried your solution:

request = new Request.Builder()
                    .url(Fiskaly.API + "/tss/" + tssId + "/tx/" + transactionId + "?last_revision=" + transactionResponseMap.get("last_revision"))
                    .put(RequestBody.create(Fiskaly.objectMapper.writeValueAsString(body), MediaType.parse("application/json")))
                    .build();

But I got the same message:
querystring.last_revision should be integer

Yes, it works here. Can you println the value that you give into the url.

[cjaentsch]

If you do not have a last_revision because it's the creation (on PUT), then don't add the query parameter at all. "null" or empty does not seem to be a valid value.

last_revision do not exists...
I need to use "revision" or "latest_revision"
Thank you very much for your help @cjaentsch
