Jwt strings must contain exactly 2 period characters. found: 0

JWT (JSON Web Token) is a format used to securely transmit information between two parties as a JSON object. It consists of three parts: header, payload, and signature, separated by period characters (‘.’). This format should have exactly 2 periods to be considered valid.

In your case, the error message “jwt strings must contain exactly 2 period characters. found: 0” indicates that the JWT string you provided does not have the expected structure as it doesn’t contain any period characters.

Here is an example of a valid JWT string:
“eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c”

Explanation of the example:
1. Header: “eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9” is a base64-encoded JSON object containing information about the cryptographic algorithm used and the token type.
2. Payload: “eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ” is a base64-encoded JSON object containing the claims or statements about the token.
3. Signature: “SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c” is the cryptographic signature created by combining the encoded header, payload, and a secret key.

Make sure to check your JWT string and ensure that it has exactly two period characters for it to be considered a valid JWT.
