8.x-1.2 not compatible with PHP 7.4

Hello,

Same here after update on D9.5.9:

Parse error: syntax error, unexpected '|', expecting ';' or '{' in /home/www/sited9/web/modules/contrib/fixed_block_content/src/Normalizer/BlockContentNormalizer.php on line 22

Rollback to previous for the moment.
Downgrading drupal/fixed_block_content (1.2.0 => 1.1.0)

This affects both 8.x-1.x-dev and 8.x-1.2, since union return types were made available in php 8. Would using phpdoc annotations be an alternative?

Looks like the change to src/Normalizer/BlockContentNormalizer.php was just added from the automated patch for Drupal 10 readiness in this commit. Does PHP 8.1 require union types? If not, I think that this part could be left out to support older versions of PHP.

PHP 8.1 does not require to use union types. They help because PHP detects when the wrong type is used and the type can be either one or another type.
For backward-compatibility, they should not be used. I would rather use them in a branch that requires PHP 8.1.

Hello

Still there, so which version can we use on D9.5.10 ?
[error] ParseError: syntax error, unexpected '|', expecting ';' or '{' in Composer\Autoload\includeFile() (line 22 of /home/www/xx/sited9/web/modules/contrib/fixed_block_content/src/Normalizer/BlockContentNormalizer.php) #0 /home/www/xx/sited9/vendor/composer/ClassLoader.php(428): Composer\Autoload\includeFile('/home/...')

Thanks

I guess until this is committed, on Drupal 9 stick to https://www.drupal.org/project/fixed_block_content/releases/8.x-1.1 → . But I don't see a big chance for that since PHP 7.4 is EOL and everyone should migrate to a newer PHP to stay secure, plus Drupal 9 is close to the November 2023 EOL, too.

Drupal 10 works on PHP 8.1<= only, so there should be no problem there. If the maintainer does not wish to fix this issue, then the required minimum PHP version should be stated in the module's composer.json at least.

Apparently removing the union types makes the module incompatible with HAL 2.x, which is required for Drupal 10. Drupal 9 can use HAL 1.x.

Hello, this explain why it's impossible to update HAL too.
drupal/hal 1.0.3 2.0.1 Hypermedia Application Language (HAL)

We need a HAL < 2.x compatible normalizer class. Initial approach.
