ravillarreal opened a new issue, #12932:
URL: https://github.com/apache/apisix/issues/12932
### Current Behavior
Im using apisix, with standalone mode, in which ive noticed that when a env
variable is set in apisix.yaml file, if the value is a number, it will
automatically convert it to number, and this causes an error if the number is
bigger than Lua's double, for example (extracted from my apisix.yaml file):
```
plugin_configs:
- id: 1
plugins:
openid-connect:
client_id: "${{APISIX_OIDC_CLIENT_ID}}"
```
Note the double " in the env var, still it doesnt treat it like an string
The APISIX_OIDC_CLIENT_ID is set to "356002209726529540" but the value is
casted to `"client_id":3.5600220972653e+17`
This is because this code in apisix/cli/file.lua
https://github.com/apache/apisix/blob/a269d61a5b115f9350293c47c2551597efc5487c/apisix/cli/file.lua#L127C17-L128C48
### Expected Behavior
I expect that the value passed in as "${{var}}" works like an string
### Error Logs
`2026/01/22 06:11:11 [error] 57#57: *321192 [lua] config_yaml.lua:333:
failed to check item data of [plugin_configs] err:failed to check the
configuration of plugin openid-connect err: property "client_id" validation
failed: wrong type: expected string, got number ,val:`
### Steps to Reproduce
1. Run APISIX via the docker image
2. Configure it as standalone mode with env variable -
APISIX_DEPLOYMENT_MODE=standalone
3. Configure env variable with number inside bigger than lua's double eg
"356002209726529540"
4. Set the variable in apisix.yaml in "${{}}" format
5. Get the error, in this case im using openid-connect plugin
