In test.env at line 1, the environment variable assignment for DATABASE_URL is
missing the '=' delimiter. Add an '=' between the key and the value so the line
reads DATABASE_URL=postgres://user:pass@localhost:5432/dbname to ensure proper
parsing by .env parsers.

In test.env at line 2, remove any spaces around the equals sign in the
assignment to API_KEY so that it reads exactly "API_KEY=someapikey" without
spaces before or after the "=" to ensure the value is parsed correctly without
leading or trailing spaces.

In test.env at line 3, the SECRET_KEY is set to a real-looking secret which
should not be committed to version control. Replace the current SECRET_KEY value
with a placeholder value that does not expose any real credentials, and move the
actual secret to a secure secret store or an untracked file like .env.local to
keep it out of the repository.

In test.env around lines 4 to 5, the environment variable names are invalid
because they start with digits or contain hyphens, which is not allowed. Rename
the variables so that they start with a letter or underscore and only contain
uppercase letters, digits, or underscores. For example, change "123TOKEN" to a
valid name like "TOKEN123" and "API-KEY" to "API_KEY".

In test.env at line 6, the PASSWORD value contains unescaped double quotes
causing unterminated string issues. Fix this by either wrapping the entire
password value in single quotes or escaping the inner double quotes properly to
ensure the string is correctly parsed.

In test.env at line 7, the inline comment after the REDIS_URL value is being
parsed as part of the value, which is not supported by most dotenv loaders.
Remove the trailing comment from the same line and place the comment on a
separate line above or below the REDIS_URL entry to ensure correct parsing.

In test.env around lines 9 to 10, the environment variable DUPLICATE_KEY is
declared twice, which causes the first declaration to be ignored and can lead to
confusion or errors. Remove one of the duplicate declarations or rename one of
the keys to ensure each environment variable is unique and avoid silent
overwriting.

In test.env at lines 12 to 13, the environment variable MULTILINE_VAR is split
across two lines without proper quoting, which breaks the file parsing. To fix
this, rewrite the value as a single line string enclosed in quotes and use \n to
represent the line break inside the quotes, ensuring the entire value is
contained on one line.

In test.env at lines 17 to 18, remove the leading space before SPACED_VAR and
add an equals sign for MISSING_EQUALS_SIGN to correctly assign its value. The
corrected lines should have no leading spaces and use the format VARIABLE=VALUE.

In test.env at line 19, the value for BAD_QUOTES is missing a closing single
quote, causing an unterminated string. Fix this by adding the closing single
quote at the end of the value or replace the single quotes with double quotes to
properly terminate the string.

In test.env at line 20, the variable INVALID_UTF8 contains invalid UTF-8 escape
sequences \x80\x81\x82 which may cause issues. To fix this, either remove the
INVALID_UTF8 variable entirely or replace its value with a base64-encoded string
representing the intended bytes to ensure safe loading and compatibility with
UTF-8 systems.
