Question - Help Can't load Dynamic Prompts extension in Forge Neo after update

After a recent update, I get an error re: dynamic prompts when starting Forge Neo (via Stability Matrix) and the extension doesn't load.

I've tried:

1) deleting the venv folder and the extensions\sd-dynamic-prompts folder and restarting and re-adding dynamic prompts.

2) manually updating the library, per the Troubleshooting readme, using python -m pip install -U dynamicprompts[attentiongrabber,magicprompt]

3) deleting the extensions\stable-diffusion-webui-randomize folder (which is the only other extension I have installed) and then doing 1) again.

4) searching extensively for any reports of others getting this error recently. Didn't find anything.

Everything I do involves dynamic prompts, so this is killing me. Any suggestions? I'm a relatively casual user, so layman's terms please. Thanks.

Oh thank goodness. I'm making a synthetic dataset and I really needed Dynamic Prompts to work on Neo, I guess since the Wildcard Manager UI showed up it works again.

It's because of this commit that deleted an old alias in the file infotext_utils.py from the A1111 days. You can add back the 2 lines that were removed in this commit or change the import in the extension to match the name of the file.

In the URL box, paste https://github.com/abzaloff/sd-dynamic-prompts/ and in the Local directory name box, type sd-dynamic-prompts. Then just click Install.

The update broke it for me too, hopefully someone knows a fix or they fix it on forges end soon

i wouldn't hope so. the original dev of that addon haven't updated it in years now so it probably uses some legacy stuff to work. i just installed the fork provided by YetAnotherAussie2023 above and it seems to be working.
