TACO Signature Verification Fails with Error "Path does not chain with any of the trust anchors"

Julkaisupäivä: Feb 23, 2026
Kuvaus

When creating a connection using a connector built with the Tableau Connector SDK, the following error may occur:

Error Code: 14D18B1F
Package signature verification failed during connection creation.

Additionally, the following error messages are found in log.txt in the Tableau Desktop logs folder:

Taco is unsigned or the signer certificate is not trusted.
Path does not chain with any of the trust anchors

Cause

The root certificate used for signing the connector.taco package is not present in the system trust store.
Ratkaisu
1. Examine the Tableau Desktop log file (log.txt) for the signer certificate chain. For example, the following lines can be found in the logs when using the Starburst Enterprise connector file: 
Signed by:
CN="Starburst Data\\, Inc.", O="Starburst Data\\, Inc.", L=Boston?, ST=Massachusetts, C=US
CN=SSL.com Code Signing Intermediate CA RSA R1, O=SSL Corp, L=Houston, ST=Texas, C=US
CN=SSL.com Root Certification Authority RSA, O=SSL Corporation, L=Houston, ST=Texas, C=US
CN=Certum Trusted Network CA, OU=Certum Certification Authority, O=Unizeto Technologies S.A., C=PL
2. Work with your IT team to locate a reliable source for the root certificate (the last certificate in the list), and install the certificate in the system trust store. In the above example, the root certificate is Certum Trusted Network CA and the certificate (CTNCA.crt) can be downloaded from the Certum root certificate repository.
