Internal Server Error

[Rika Tateyama]

Hi there.

When you press the Action button in Flow designer, the
The "Internal Server Erro" screen will appear as shown in (1) image below.

Also, if you click the Test button and enter a value, the screen shown in (2) image will appear.

How can I solve this problem?
I would appreciate it if you could provide a solution.

Hi, unfortunately partial screenshots of a flow, provide no information that the forum can use to assist in diagnosis of your issue.
Perhaps you can update this thread with clear and specific information of your flow, underpinning platform configuration and the results of your debugging; so that the forum is in a better position to review and advise.

Thank you your advice.
