[Bug] Method not found Exception when reading JWT token (Base64UrlEncoder.UnsafeDecode)
Which version of Microsoft.IdentityModel are you using? 7.5.1
Where is the issue?
- M.IM.JsonWebTokens
Is this a new or an existing app?
Repro
I am just trying to add JWT authentication to the existed app
services.AddAuthentication()
.AddJwtBearer(JwtBearerDefaults.AuthenticationScheme, options =>
{
options.Audience = apiName;
options.Authority = identityServerUrl;
});
Expected behavior Acess token successfully validated
Actual behavior A clear and concise description of what happens, e.g. an exception is thrown, UI freezes.
Possible solution I am getting exception:
IDX14100: JWT is not well formed, there are no dots (.).
The token needs to be in JWS or JWE Compact Serialization Format. (JWS): 'EncodedHeader.EndcodedPayload.EncodedSignature'. (JWE): 'EncodedProtectedHeader.EncodedEncryptedKey.EncodedInitializationVector.EncodedCiphertext.EncodedAuthenticationTag'.
Which has inner one with message:
Method not found: 'Byte[] Microsoft.IdentityModel.Tokens.Base64UrlEncoder.UnsafeDecode(System.ReadOnlyMemory`1<Char>)'.
With call stack:
at Microsoft.IdentityModel.JsonWebTokens.JsonWebToken.ReadToken(String encodedJson)
at Microsoft.IdentityModel.JsonWebTokens.JsonWebToken..ctor(String jwtEncodedString)
at Microsoft.IdentityModel.JsonWebTokens.JsonWebTokenHandler.ReadToken(String token, TokenValidationParameters validationParameters)
Additional context / logs / screenshots / links to code
I double checked all dependencies, and they look good for me.
