body type string is not recognized

[gonenduk]

Thanks! That was the problem :)
In the code I added:
app.use(express.json());
app.use(express.text());

Note: In the example above there is also an enum on the string value, but it can be removed for this sample. The issue is with the string type - not the enum.

@gonenduk Can you ensure you are able to parse body text

For example, ensure you're express app is set up to to parse both text and json bodies. For example, you might use the bodyParser middleware:

e.g.

app.use(bodyParser.text());
app.use(bodyParser.json());

i have a hunch that perhaps everything is forced to json and thus the validator is getting req.body with a value of empty JSON object e.g. {}, rather than the expected string value e.g. whatever string the caller PUT

assuming this is the case, the validator should, at least, throw some kind of validation error stating that it received JSON not {} text instead of a string value (and if it can distinguish, perhaps a note about the body parser to help dev's sort the issue or even)

also, assuming this is the case, i wonder if the validator should optionally install relevant body parsers. something like this may overstep the scope of the validator. users should have choice. food for thought. if you have opinions, please share

Fantastic! I added some notes to the README. Do you feel the validator should do more here, that is beyond some notes in the README it.

Not sure there is anything you can do in the validator in this case.
Maybe extend the error message after saying it should be a string, add the type you got - in my case i believe it was undefined (it was not a json and there was no parser for text so req.body left undefined)
maybe adding the typeof req.body to the error message info will help. But I'm not so sure about this.
