I named a logic apps workflow with a space character and I cannot open the Workflows page within the Logic App resource.
What can I do?

The overview provides details of the cause.User's image

The workflow page error is more general (in both newer experience and original experience)

Some researches led me to these two issues reported that are similar :

https://github.com/Azure/LogicAppsUX/issues/6252
https://github.com/Azure/LogicAppsUX/issues/8537

I need help ASAP.

Thank you,

    Thank you SO SO much !
    You are amazing !

    I couldn't rename the flow from Kudu though (didnt find how to).
    But I could download the flow as a JSON and delete it.
    Then I recreated it from the JSON.

    Thank you again, very very much.

    Hello Damien Size,

    You’ve run into a known issue in Azure Logic Apps (Standard) where a workflow created with an invalid name (like one containing spaces) breaks the Workflows blade and prevents it from loading.

    Root cause: Get AR Invoices - TEST workflow contains Contains spaces, which are not supported, Allowed characters only: A–Z, a–z, 0–9, -, _, (, )

    To resolve this issue please follow below steps:

    Open Kudu: Logic app> development tools> advanced tools > click on GO.

    Debug Console → CMD → site/wwwroot/workflows

    User's image

    User's image

    User's image

    Locate - Get AR Invoices - TEST

    and rename it. like: GetARInvoices_TEST

    Finally restart the logic app.
