getTag not returning the scanned tag, techRequestCallback is null

[tastydev]

Hey,

i currently have trouble scanning IsoDep tags. It sometimes just don't wanna work somewhere inside the App while it works in other places.

Based on the logs and breakpoints i set to investigate i can see that the tag is scanned but the techRequestCallback is null

Can you tell me what this case means and how it could be provoked?

Thanks.
