Android Question ResponseError. Reason: Internal Server Error, Response: Error 500

[Angelo Messina]

Hi, my App which has always worked very well by connecting to the "Agenzia delle Entrate" website by sending payments via a signed xml file, has not worked since 21 November 2022 with an error message:
ResponseError. Reason: Internal ServerError, Response:
returning error 500
Do you have any advice for me?
Thanks in advance
Sincerely

 

[DonManfred]

Do you have any advice for me?

contact the site-admin and ask about this problem. 500 is an server-error.

HTTP response status codes - HTTP | MDN

HTTP response status codes indicate whether a specific HTTP request has been successfully completed. Responses are grouped in five classes:

developer.mozilla.org

Usually the 500 error is an internal problem of the Server

 

[Angelo Messina]

the same procedure with the same java library works with a app java

 

[Angelo Messina]

I was wondering may it depend on the OkHttpUtils2 library

No.

 

[DonManfred]

same java library

what java library?

works with a app java

what app java?

 

[Angelo Messina]

a library written by me for signing the xml
I always use http

 

[Angelo Messina]

moreover, with a similar program in Windows 11, the "Agenzia delle Entrate" site does not give an error and takes the xml files without problems. so it's something that happens with Apps generated with B4A

 

[Angelo Messina]

I don't know what could be the cause

 

[Angelo Messina]

No.

Credo che c’è qualcosa che non va con questa libreria perché il file xml trasmesso al sito direttamente funziona

The library okhttputils works fine.
Look at the inserted parameters that you use to transmit the same and verify that they are present.
Sorry if write in English but we are on the international site

 

[MarcoRome]

Another question is the first one you send to the agency ( with App ) or did you send others and suddenly it generated a 500 error?

 

[Angelo Messina]

sorry for writing in Italian, copy paste error

 

[Angelo Messina]

no after 2 years of error-free transmissions from 21 November the revenue site no longer accepts but responds with a 500 error

 

[Angelo Messina]

        job1.PutString(apiEndPoint,activateDeviceXmlSigned)                ' Dai documenti: PUT
        job1.GetRequest.SetContentType("activate")
        job1.GetRequest.SetHeader("Accept=","application/xml")
        
        Wait For (job1) JobDone(job1 As HttpJob)
        nCode = job1.Response.StatusCode
        Log(nCode)

So if I understand correctly you have been using the app with okhttputils for two years and has it always gone well?
If so, did you upgrade to B4A?

 

[Angelo Messina]

Yes, yesterday I did the update, after several tests, but nothing changes

 

[MarcoRome]

If you did it yesterday but you've had the problem since November 21st then it's not that.
Try sending the request via postman with the same parameters you use in B4A and see what it returns.
It could be that they changed some parameter
