Hello all,

This is a problem that I’ve been struggling with for almost a week now. I’ve found several posts with the same error message, but the cause seems to be different from mine in every case; none of the fixes seem to apply to me. I’m getting the following error:

[29512] Failed to execute script EmailBuilderPrompt

Here’s the twist: I created an executable of my file using pyinstaller, and it’s only when I run the executable that I run into this problem. If I run the file as Python, I have no problem at all. But I need it to be an executable, because I can expect all the users to install all the various modules and dependencies required for the script. Can someone please help me? I’m using plotly version 4.1.1.
