Matsalar da aka rasa #[max_len(32)] ita ce, asusun da aka jera yana ɗauke da string da aka cika da 0 bytes don yin 32 bytes, yayin da tsarin da ake cire jerin abubuwa yana ƙoƙarin cire adadin bytes ɗin da string ɗinka yake da shi a zahiri sannan sauran 0 bytes ɗin suna lalata shi don cire filayen da suka biyo baya.
Don gyara wannan, ina ba da shawarar yin amfani da declare_program! daga anchor_client. Ta haka ba za ka buƙaci aiwatar da tsari ɗaya da hannu a cikin shirinka da abokin ciniki ba kuma za a aiwatar da cire jerin abubuwa a gare ka kyauta. Kwafi daga wannan tambaya:

Idan ba za ka iya yin wannan ba, ina ba da shawarar yin amfani da BorshDeserialize::deserialize kamar yadda na faɗa matsalarka ita ce samun bytes da yawa.
