Bom dia (boa tarde ou boa noite) a todos e todas, sempre que tento criar um novo fluxo é exibida a mensagem de erro abaixo:


Mensagem = Object reference not set to an instance of an object.
Erro = System.NullReferenceException

Já removi o power automate, reiniciei a máquina, reinstalei, mas não funciona, não consigo resolver. Vocês podem me ajudar com isso?

    What version you are currently using? Did you recently upgraded your PAD version? Please consider to keep 2.39 and see if it resolves your issue.

    Bom dia, @Deenuji. Verifiquei que eu não tinha acesso para atualizar a versão do PAD na máquina virtual. Solicitei ao time da TI que atualizasse a versão e o problema foi resolvido. Obrigado pela atenção e pela dica. 

     

    Vou aproveitar a oportunidade e te pedir uma sugestão: preciso criar uma automação para realizar uma atualizazação no cadastro de estoque de material. São dois sistemas que não "conversam" entre si. Sempre que alguém incluir determinados dados no sistema A será incluído um novo registro nma planilha do Excel. Preciso obter os dados dessa planilha (sempre que for inserida uma nova linha), ou seja, sempre que um novo registro for incluído preciso incluir estas informações no sistema B. Lhe pergunto: qual sua sugestão de gatilho para acionar o fluxo?

    @Marcos2023 

    If my understanding is correct, whenever new data is added to system A, a new Excel file will be generated, correct? If so, where will this Excel file be stored? Can it be stored in a specific folder?

    Excel online, você consegue colocar a criação da linha como um gatilho para um fluxo cloud, que irá chamar o desktop.

    Eu não aconselho fazer isso, pois se a frequência de criação de linhas for grande, pode disparar muitas vezes o fluxo e causar algum conflito. Creio que é melhor você agendar o fluxo com uma certa periodicidade que atenda sua necessidade e processe todas as linhas pendentes de uma vez.

    Isso, a planilha ficará numa pasta específica e sempre que uma nova linha for incluída preciso acionar o fluxo de desktop para que esse registro seja incluído no sistema B.

    If you're referring to a local machine folder rather than any SharePoint or OneDrive folder. In that scenario,

    first, install the On-Prem data gateway from the following link:

    https://powerapps.microsoft.com/en-us/downloads/

    Next, install the data gateway using the following link:

    https://learn.microsoft.com/en-us/data-integration/gateway/service-gateway-install 

    Deenuji_0-1711980186655.png

     

    Once installed, our gateway name will appear in the gateway menu as shown below:

    Afterward, utilize the "when a file is created" trigger to select your local folder as the trigger point in the cloud flow.

    Click on the three dots and select "New connection". 

    Deenuji_3-1711980186513.png

     

    Create your new connection as shown below, choosing the recently created gateway name from the last dropdown list.

    Once everything is set up, select the location of your local drive folder where you want to monitor for any file uploads or creations

    Finally, after setting up the drive folder, you can add a desktop flow to invoke when somebody creates a new file in the specified folder. The gateway will act as a bridge between your local system and the cloud flow.

     In case if you referring OneDrive folder then you can create your cloud flow like this

    Below is another trigger option in case if you refer share point folder
