Describe your question in detail.

Hello everyone,
I'm running into an issue when using an aptos-connect wallet to interact with a function in my custom Aptos Move module. Whenever I attempt to call the function, I receive the following error:

Additional context:

• I get the same error even when interacting with the function via the Aptos Explorer.

• The exact same logic works perfectly when using Petra wallet.

• The error only occurs with some FA values passed as arguments—others work fine.

• I’ve verified that all values are valid hex strings prefixed with 0x.

Thanks in advance!

What error, if any, are you getting?

Unexpected error

Hex string is too short, must be 60 to 64 chars long, excluding the leading 0x. You may need to fix the address by padding it with 0s before passing it to fromString (e.g. .padStart(64, '0')). Received 0x123

What have you tried or looked at? Or how can we reproduce the error?

can you pad the address manually? petra probably pads it automatically but connect doesn't
