Trouble loading the streamlit_ace.ace component

Using Streamlit
1

I have a strange problem that occurs randomly.
I have deployed a streamlit app that uses streamlit_ace editor. When I visit the web page, I get the following error
sometimes and other times it works fine!

Your app is having trouble loading the streamlit_ace.ace component.

(The app is attempting to load the component from **, and hasn't received its "streamlit:componentReady"** message.)

If this is a development build, have you started the dev server?
If this is a release build, have you compiled the frontend?

I have it deployed here and here
It works consistently when run from my laptop with the exact same dependency and versions installed.
here’s the output when the app is run locally.

I don’t think this is an issue with streamlit-ace, however, I had posted an issue here
If it helps, the source is hosted here

I am hoping someone here might recognise the issue and guide me.

Hi @iamashwin99 , did you solve this? I’m having the same issue

No, I had no luck, could you explain the circumstance of your issue, maybe we can trace commonalities

Having same issue but only if I turn the _RELEASE to true.
But in case of development its working fine…

Are you using a recent version of Streamlit? This bug should’ve been addressed at the end of May this year, so version 0.82+ or so?

Best,
Randy

Hi,
Are there any updates on this?
I’m having the same issue as @PSEUDO
When working locally with the dev server it works fine. After building/compiling the frontend and changing the _RELEASE to True I get this message…

Using streamlit==1.11.1

My code/component is here

Hey all, :wave:

Just wanted to update that the latest Streamlit version 1.32.2 is out and includes a significant improvement for custom components! The timeout warning was replaced with an element skeleton to improve the UX for slow-loading components, especially in some cloud-hosted platforms.

Feel free to install the latest version and let us know what you think!
