Hi, @hozaifaaoud, I checked this situation and reproduce this issue. It's occurred because APISIX support consumer name start with number, but APISIX-Dashboard does't support. Does the APISIX-Dashboard need to support consumer that start with number ?

@juzhiyuan @nic-chen @starsz Any suggestions?

we should keep the same with APISIX.

@zaunist Please see https://github.com/apache/apisix/blob/master/apisix/schema_def.lua#L693 , may need to keep the regex the same as apisix.
