get_number_of_pools misbehaving

[mikedotexe]

Looking at Eugene's token factory:

https://github.com/evgenykuzyakov/token-factory/blob/15aae092a4cae928f119140632af0512448071ae/frontend/src/Tokens.js#L343

we run into an issue

Error: Querying call/ref-finance.near/get_number_of_pools,AQ4 failed: wasm execution failed with error: FunctionCallError(CompilationError(PrepareError(Deserialization))).
{
  "error": "wasm execution failed with error: FunctionCallError(CompilationError(PrepareError(Deserialization)))",

Running this command on NEAR CLI also throws the same error:

NEAR_ENV=mainnet near view ref-finance.near get_number_of_pools
