Nova on Laradock raises bcadd exception

Question

I have a simple installation of Laravel with Laradock.
When I try to update a model, there is no problem.

However, when I install Nova and try to update some model (for example user name), I get the following error:

Looking at ajax call, I see the following error:

exception: "Symfony\Component\Debug\Exception\FatalThrowableError"
file: "/var/www/vendor/moontoast/math/src/Moontoast/Math/BigNumber.php"
line: 506
message: "Call to undefined function Moontoast\Math\bcadd()"

I tried to set PHP_WORKER_INSTALL_BCMATH to true in .env and rebuild docker image, but it didn't help.

I also found this issue:

But it didn't help me to solve the problem.

Answer 1

For anyone else experiencing this issue this is what solved it for me: bin/bash into docker container and run

docker-php-ext-install bcmath

Then restart server. This helped for my case. I would expect analogical steps would work for Laradock.
