## The argument "arguments" was registered with type "array", but is of type "string" in view helper

This problem is related to the use of an extended Fluid syntax
like this:

```
<a href="{be:moduleLink(route:'system_reports',arguments:{action:'detail', extension:extensionKey, report:reportName})}">

```

In some versions of PHP, there is a PCRE bug with the underlying
`readline` library:
[https://github.com/TYPO3/Fluid/commit/865890c3cffaf8d5f6aa44295d42a84a103895ec](https://github.com/TYPO3/Fluid/commit/865890c3cffaf8d5f6aa44295d42a84a103895ec)

A possible fix (for the example above) is to enclose the array arguments
with single quotes like that:

```
<a href="{be:moduleLink(route:'system_reports',arguments:'{action:\'detail\', extension:extensionKey, report:reportName}')}">

```

This effectively forces Fluid to extract the content of the single
quotes with a simpler regular expression instead of a recursive one.

The argument does not follow the
[Fluid array syntax](https://docs.typo3.org/m/typo3/guide-extbasefluid/main/en-us/Fluid/ThingsToKnow/Arrays.html).

```
<f:render section="someSection" arguments="foo: {someVariable}" />

```

Solution:

```
<f:render section="someSection" arguments="{foo: someVariable}" />

```

Another possible cause of this error may be a PHP-configuration problem:
PHP 7.3.14:

```
pcre.jit = 1

```

jit (Just in time compiler) had to be enabled in my installation.
