A reproducible example At least as much as I can: from azure.identity import ChainedTokenCredential, ManagedIdentityCredential, AzureCliCredential azure_cli = AzureCliCredential() managed_identity = ManagedIdentityCredential() CREDENTIAL_CHAIN = ChainedTokenCredential(managed_identity, azure_cli) import pandas as pd ***@***.***/path_to_parquets.parquet", storage_options={"credential": credential_chain}) print("Done") I do get the "Done" printed before failure. My config ubuntu, python 3.10, azure-storage-blob==12.16.0 pandas==2.0.0 pyarrow==11.0.0 adlfs==2023.9.0 — Reply to this email directly, view it on GitHub <#431> or unsubscribe <https://github.com/notifications/unsubscribe-auth/AAKAOIVBR7SYSQMVOV7SKMTX6ARJZBFKMF2HI4TJMJ2XIZLTSOBKK5TBNR2WLJDUOJ2WLJDOMFWWLO3UNBZGKYLEL5YGC4TUNFRWS4DBNZ2F6YLDORUXM2LUPGBKK5TBNR2WLJLJONZXKZNENZQW2ZNLORUHEZLBMRPXI6LQMWBKK5TBNR2WLJDUOJ2WLJDOMFWWLLTXMF2GG2C7MFRXI2LWNF2HTLDTOVRGUZLDORPXI6LQMWSUS43TOVS2M5DPOBUWG44SQKSHI6LQMWVHEZLQN5ZWS5DPOJ42K5TBNR2WLKJRGA4TIMBRHE4TTAVEOR4XAZNFNFZXG5LFUV3GC3DVMWVDCOJTGA2DOMBSGA2KO5DSNFTWOZLSUZRXEZLBORSQ>.
