Trying to access array offset on value of type null

[garak]

This stopped working on php 7.4, for example on DocParser class
See https://twitter.com/nikita_ppv/status/1148931277216800769 for a reference

Ref:

annotations/lib/Doctrine/Annotations/DocParser.php

Line 983 in 793b91a

while ($this->lexer->lookahead['position'] === ($this->lexer->token['position'] + strlen($this->lexer->token['value']))

[rbairwell]

If it helps, the following seems to fix the problem:
while ($this->lexer->lookahead!==null && $this->lexer->lookahead['position'] === ($this->lexer->token['position'] + strlen($this->lexer->token['value']))

Symfony also has alot of failures in php 7.4 due to this, ref. symfony/symfony#32844

Will the fix be merged into master in the near future? I'm testing 2.0 on PHP 7.4-beta4, and am blocked. Thanks!

Does this still seem to be broken?

ErrorException : Trying to access array offset on value of type null
vendor/doctrine/annotations/lib/Doctrine/Common/Annotations/DocParser.php:995

while ($this->lexer->lookahead['position'] === ($this->lexer->token['position'] + strlen($this->lexer->token['value']))

@SuperlativeEntity what version are you running? This has been fixed in 1.7.0.

[SuperlativeEntity]

Okay, my mistake, I have the wrong version. Thanks for your time.

I'm using version 1.10.2 and it's failing in other line:

[ErrorException]
 Trying to access array offset on value of type null
in /code/vendor/doctrine/annotations/lib/Doctrine/Common/Annotations/DocParser.php:1047

[SuperlativeEntity]

@javiyt Did you resolve the issue?

[javiyt]

No

[SuperlativeEntity]

Might be easier to just log a separate issue.

Does this still seem to be broken?

ErrorException : Trying to access array offset on value of type null
vendor/doctrine/annotations/lib/Doctrine/Common/Annotations/DocParser.php:995

while ($this->lexer->lookahead['position'] === ($this->lexer->token['position'] + strlen($this->lexer->token['value']))

This fixed the issue in my case:

while (isset($this->lexer->lookahead['position']) && $this->lexer->lookahead['position'] === ($this->lexer->token['position'] + strlen($this->lexer->token['value']))

[SuperlativeEntity]

We can't just edit the vendor files, it needs to be fixed in the package.

[Ocramius]

Hey folks: posting here won't help.

Please raise a new issue with associated failing test case, so it can be solved there.

[wiistriker]

still error on php 7.4

[ma-gu-16]

Confirm, still error on PHP 7.4 and current symfony flex doctrine/orm v 2.7.5

Current PHP version is 7.4, should I downgrade to 7.3 or upgrade to 8?

[Ocramius]

@thewasta please report it to akeneo/pim-community-dev - it has nothing to do with doctrine/annotations.
