Error when using custom classification block

I created a custom classification block on VScode and it has the same structure as when you select edit block locally. I’ve been reading the documentation and followed the steps. Once the training was done and the rained model was stored in the out folder, I created a block and pushed it with edge-impulse-blocks push with the cmd directory on the same path as the project folder. It created a custom block but when using it in edge impulse and error appears and it says that there is no metadata, and block has not been trained. How can i solve this?
Here it is the screen cap:


Here is my block in Machine Learning blocks page:

The training terminal output is this:

Hi @JosuGaztelu,

Did you use the CLI tool to create your block template (Blocks - Edge Impulse Documentation)?

You also might want to check the metadata given in as compared to a known good learning block, such as this one: GitHub - edgeimpulse/example-custom-ml-block-ti-yolox: YOLOX block from TI

Yes, I followed the steps and didn’t work.
Anyway, I used the template from edgeimpulse/example-custom-ml-block-keras: Custom Keras ML block example for Edge Impulse ( and it did work so I just changed the structure of the network for the actual project and it worked.
