Below is a new question with the following picture and attachment, thanks
Click to expand...
1. Log the map variable that you need to be adding / updating to the database.
2. Check that the map keys match the field names in the database table.
3. If one of the columns in the database table is auto-increment, remove its key from the map for Create???
4. Rather log(strError) so that you can see the complete error so that you are able to fix it.

In most cases this error is causes by a mismatch of field names and the auto-increment field issues.

Good luck!

Tip: Using locally hosted resources i.e. CSS and JS files

You might want to do this during the development of your project... In release mode, rather use the CDN versions of the resources (if available)

In case you are in a place with an erratic internet connection, and one would rather host the library resources themselves.

1. Open the BVAD3 library, go to main. You will see this...

B4X: 
BANano.Header.AddCSSFile("https://fonts.googleapis.com/css?family=Roboto:100,300,400,500,700,900")
BANano.Header.AddCSSFile("https://cdn.jsdelivr.net/npm/@mdi/font@latest/css/materialdesignicons.min.css")
BANano.Header.AddCSSFile("https://cdn.jsdelivr.net/npm/vuetify@2.x/dist/vuetify.min.css")
BANano.Header.AddJavascriptFile("https://cdn.jsdelivr.net/npm/vue@2.x/dist/vue.min.js")
BANano.Header.AddJavascriptFile("https://cdn.jsdelivr.net/npm/vuetify@2.x/dist/vuetify.min.js")
BANano.Header.AddJavascriptFile("https://cdn.jsdelivr.net/npm/vue-router@3.x/dist/vue-router.min.js")
BANano.Header.AddJavascriptFile("https://cdn.jsdelivr.net/npm/dayjs@1.9.6/dayjs.min.js")
BANano.Header.AddJavascriptFile("https://cdnjs.cloudflare.com/ajax/libs/numeral.js/2.0.6/numeral.min.js")
BANano.Header.AddJavascriptFile("https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.20/lodash.min.js")

2. Copy each CDN link and then download each file to your PC.
3. After you have downloaded the resources, copy and paste them to your BVAD3 library project, if the library is opened, ensure you refresh the "Files" tab.
4. For the font files, you will need to also download the relevant font files. For example, for roboto, you get a css.css file.

You will get the URL links inside the files... copy and then download each of the files referenced inside css.css. Then update your css.css file to reflect. Save this file as roboto.css



The file names provided here are "other" names, I have renamed them for brevity. You can then rename the files accordingly. Also ensure you change the URL to point to ../assets

Copy the font files to your BVAD3 project "Files" also and sync your "Files"

5. Head over to https://materialdesignicons.com/ to download the font files.
6. Copy the materialdesignicons.min.css to your "Files",
7. Copy the contents of the "fonts" folder from your download also to the "Files"
8. The next step is to update the URL inside the materialdesignicons.min.css. These have ../fonts, you needs to rename this to be ../assets



9. Save your file.
10. Update the Header.AddCSS and AddJavascripLinks. This should now reflect.



When in production mode, you can then switch between locally hosted resources and CDN based versions by toggling the comments below.



All the best.

@Johan Hormaza I have not released any tutorial for the jrdc2 but only asked a question as I had issues with it also. Im sorry I cannot comment or help you on any jrdc2 related issues.

Until the question I asked is resolved I am not at liberty to talk about this particular issue.

So please don't use any jrdc related stuff on this library.

Update:

The same question was posted on Sunday and have not been resolved:

[BANanoServer] [SOLVED] Request assistance with jRDC2 error with ResumableSub

Ola Download I'm attempting to implement jRDC2 with my test project with the BANanoServer. I am able to perform CREATE, UPDATE, DELETE calls, however each of them results in an error. Line 41203 has this kind of code. // [26] Public Sub Initialize _B.initialize=function() { // [29] If...

Tip: Using BANanoPromise with CallInlinePHPWait

NB: The promise.CallSub is LOWERCASE sensitive for methodname

We want to execute a database command and this should work via a promise call. So this returns True/False depending on whether the record exists or not.

B4X: 
'user is registering
Sub btnSignUpDo_click(e As BANanoEvent)        'IgnoreDeadCode
    login.refs = vuetify.GetRefs
    Dim fValid As Boolean = login.FormValidate("createform")
    'If fValid = true Then Return
    '
    Dim userm As Map = login.GetData("signup")
    Dim stel1 As String = userm.Get("tel1")
    
    Dim res As Boolean
    Dim err As Object
    Dim uf As BANanoPromise        'ignore
    uf.CallSub(Me, "getuserbytel1", Array(stel1))
    uf.Then(res)
    Log(res)
    uf.Else(err)
    uf.End
End Sub


Sub GetUserByTel1(suserid As String) As Boolean
    Dim rsUsers As BANanoMySQLE
    rsUsers.Initialize("db", "user", "tel1", "")
    'add field types
    rsUsers.SchemaAddText(Array("tel1"))
    rsUsers.Read(suserid)
    rsUsers.JSON = banano.CallInlinePHPWait(rsUsers.MethodName, rsUsers.Build)
    rsUsers.FromJSON
    If rsUsers.result.Size > 0 Then
        banano.ReturnThen(True)
    Else
        banano.ReturnThen(False)
    End If
End Sub
