Unexpected error when server expands a compressed message to learn it is too large

When the client uses “gzip” compression to compress requests, if it sends a message where the compressed size is acceptable (less than or equal to the server’s configured max) but the uncompressed size is too large, the client receives an unhelpful UNKNOWN error with a message of “Application error processing RPC”.

Interestingly, an error is logged with an exception that indicates the expected/correct error code. It’s not a warning but an error with a message that implies the exception was never caught:

```
