Improve Error Message for Rejected Extrinsics #375
Description
Is your feature request related to a problem? Please describe.
The nodes currently reject some extrinsics (registration/stake/unstake) for rate limiting purposes, etc.
However, the error message for any case is "Transaction would exhaust the block limits" which is not descriptive/informative.
Describe the solution you'd like
It would be good to be more informative to clients about why the extrinsic was rejected
