EternalStorage.getStringValue not working #1

Closed nrchandan closed 7 years ago

nrchandan commented 7 years ago

Hi Elena, I'm trying to use the concepts in your blog post to make my own contract upgradable. However, I'm facing problem with returning string types. Apparently, EVM cannot read variably-sized data from external function calls. Pasting the exact error message below for your reference.

Have you tackled this problem in some way?

Error: Return argument type inaccessible dynamic type is not implicitly convertible to expected type (type of first return variable) string memory.

Hi @nrchandan, indeed we cannot read strings within the solidity contracts but you can from the client side via the JS API which is what we can do via await storage.getStringValue.call([storageKey]);

Thank you for the response. Great work with the upgradable contracts! I am adopting your approach in my project too.
